Various Types Of Sand And Functions

Various Types Of Sand And Functions

To create a building of course we need the material - the best ingredients. materials - materials that we think are capable of building a solid construction and the liveable. though it may cost that will be issued to purchase the material - the material is not cheap or a little more expensive in comparison materials - materials that are commonly used. you may already be familiar with this one building materials, Sand. to buy sand or aggregate we have to choose the best, because if it gets one vote sand that will be used to build a building would be fatal later.

This sand has a different function - depending on the color and the content that is in the sand itself. and with different colors we can determine where a decent sand for the building that we are building the future. to seed itself is seen from the sand grains - grains of it, if we handheld feel rough and does not clot, the sand was not good enough for your use as a building material.

Terms Sand Good For Building

1. Fine Aggregate should consist of grains of sharp and hard with hardness index <2.2

2. If used Sodium Sulfate part destroyed a maximum of 12%

3. If used Magnesium Sulfate smooth passage up to 10%

4. Must not contain the mud more than 5%

5. If the sand slurry containing more than 5% should be washed

6. Sand should not contain too much organic matter, and should be done experiment color of Abrans-Harder with a saturated solution of NaOH 3%

7. The composition of sand grain size should have a fineness modulus of 1.5 to 3.8 and consisting of grains - grains mixed

8. For concrete with a high degree of durability to alkali sand reaction should be negative

9. Sea sand should not be used for every quality fine aggregate in concrete unless the instructions of the government agency building materials are recognized

10. Fine Aggregate used for plastering and specifications applied must meet the requirements of sand a couple

After knowing the requirements of the sand for a building, we now discuss Type - Type Sand For Building explanation is as follows.

Types and Characteristics of Wood for Construction Materials

Types and Characteristics of Wood for Construction Materials

Know the Types and Characteristics of Wood for Construction Materials, Wood is one of the building materials are often used in construction. Each timber has its own properties and characteristics both in terms of the beauty of the fiber, moisture, durability, density, density, and strength.

So in choosing wood that will be used helps us know the type and characteristics of wood Frequently Used For Construction Materials. In addition to that we may know the wood that match the criteria and specifications that we want, of course, also that we are not fooled by other types of wood.

Miscellaneous Wood for Construction Materials

Teak wood is often regarded as the most beautiful fiber and texture. Its characteristics are stable, strong and durable making it the main choice of wood as a building material. Including wood with Durability Class I, Class II and Strong I, II. Teak also proved resistant to fungi, termites and other insects because the oil content in the wood itself. No other timber that deliver quality and performance comparable to teak.


Teak trees are not the kinds of trees in tropical rain forests characterized by high rainfall throughout the year. Instead, teak forests grow well in dry areas and calcareous in Indonesia, particularly in Java. Java is the region's best quality teak trees which have started to be planted by the Dutch government since the early 1800s, and is now under the management of PT Perum Perhutani. All our teak wood Perhutani supplied directly from TPK area of ​​Central Java and East Java. We do not wear teak apart from the two areas.


Price teak influenced many of origin, size and criteria of quality wood tolerable limits, such as: there is a healthy eye, no eye dies, there doreng, there are white. Determination of the desired quality teak wood finishing applications should consider the type selected. Besides protecting the wood from outside conditions, finishing in the timber is expected to provide aesthetic value on the timber by highlighting the advantages and disadvantages of the quality of the wood.

Why sand lumajang So Competitive?

Sand from Lumajang called quality number one as a mixture of concrete. Sand from Lumajang known to contain iron (Fe) is high so as to make the concrete more robust than concrete made from sand origin other regions.

Due to high demand, the business is very promising Lumajang sand. That is why, in Lumajang sand mining rampant, even the most daring open illegal mines. Hariyono, village head Selok Awar-Awar and his men, even willing to kill Salim hare, frontman of citizens who reject the existence of their sand quarry.

A businessman in Lumajang admitted sand, sand from Lumajang over the years, mostly shipped to manufacturers of concrete material, such as poles or box culverts, especially in Surabaya. One of the big companies that supplied, he said, is the PT Merak Concrete Mix.

Not only to the city, according to the source, he had sent to Samarinda, East Kalimantan and Papua. "We tell them (the ship) barges. They like sand cement Lumajang as efficient. So the cost of production cheaper and better quality," the source said.

Businessperson other sand, a sand collectors in Lumajang calling, his business has a license. Only, he admits, he does not care who sold him the sand where it comes from, whether from legal and illegal mines. To secure their business, according to him, the collectors pay "protection money" to the local polsisi elements.

Every month, he said, he deposited US $ 3 million to the police elements. The money was worth a little impressed, according to the source, because the business is small. Temporal larger deposits, according to him, comes from illegal mining and large collectors.

He explained that he bought sand for Rp 300 thousand to Rp 400 thousand per truck, depending on the amount of trucks. He said, the sand was then sold Rp 200 thousand per cubic meter to the manufacturer of the concrete.

The collectors admitted, he only has land assets reservoir sands and the excavator. While the matter of transportation, he said, entirely a matter for sand sellers and buyers.

Sand from the seller, according to him, is usually delivered using small trucks with a capacity of 8 cubic meters. While the buyer later brought the sand using tronton truck with a capacity of 25 cubic meters.

Glass

 

 

Glass is a material lutsinar, strong, resistant hakis, lengai, and is biologically inactive material, which may be formed into a resistant and slippery surfaces. These characteristics make the glass as a material that is very useful. The main component is silica glass. Silica is the mineral that contains silicon dioxide. IUPAC name of the silicon is silicon dioxide (IV) oxide. Silica in sand form a semulajadi.

Glass is one word of solid material, usually formed when molten material is cooled rapidly berkristal, by not giving it enough time to network kekisi ordinary crystals formed.

Than ordinary glass typically consists of silicon dioxide (SiO2), which is chemically similar sebatian kuarza, or in the form polihabluran, sand. Pure silica has a melting stage about 2000 Celsius, so the other two ingredients are mixed to sand in the manufacture of glass. One thereof is soda (sodium carbonate Na2CO3), or potasy, equivalent to sebatian potassium carbonate, which lowers the melting stage to about 1000 Celsius. However, the soda makes the glass soluble material, so lime (calcium oxide, CaO) is the third ingredient, plus to make the glass insoluble.

Silicon (IV) oxide is a giant covalent molecule. Accordingly, the silicon (IV) oxide haba require much effort to overcome any covalent bonds between atoms in the structure of the giant. Thus, silicon (IV) oxide has a very high melting takat, namely 1710 C. In silicon (IV) oxide, each silicon atom is covalently bonded to 4 oxygen atoms in a tetrahedron with bond angles of 109.5. Units that are not infinitely repeated with each oxygen atom bonded to two silicon atoms to form a giant covalent molecules such as the diamond structure. Glass is one word of solid material, usually formed when molten material is cooled rapidly berkristal, by not giving it enough time to network kekisi ordinary crystals formed.

One characteristic of glass is it lutsinar. Lutsinar properties due to the glass rather than the material comprising the state has no ruler changes in the atomic power of light. Also caused the glass is one word on a larger stage than the waves of light, causing the light refracted ketidaksekataan, transmitting the image block.

Pure glass may be so lutsinar sehinggakan be penetrated by hundreds of kilometers of glass infrared light waves in optical cable gentian.

Ordinary glass has a mixture of other ingredients to change the character. Black leaded glass is more shimmering reflections kerana index increased, while the boron added to change the terms and electric characteristics, such as Pyrex. Adding barium also increases the reflection index, and cerium is used in glass that absorbs infrared energy. Metal oxides are also added to the glass color change. Improved Potash soda or melting stage lower again, while manganese added to get rid of unwanted color. Stained glass is produced by mixing with a bit of transition metal oxides. For example, manganese oxide will produce purple color, and chromium oxide kuprum give a green color, and oxides kolbalt give blue.

Soda or sodium carbonate, Na2CO3 which lowers the melting stage to about 1000 C. However, the soda makes the glass soluble material, so lime (calcium oxide, CaO) is usually added to make the glass insoluble.

Occasional glass formed by volcanic lava semulajadi than in the form of obsidia.

Kinds of wood

 Kinds of wood

Teak is a kind of high-quality timber-producing trees. A large tree with a straight-trunked, it can grow to 30-40 m high. Large-leaved, which is shed in the dry season.
Teak is known world by the name of teak (English).
Sandalwood, or sandalwood fragrance, a producer of sandalwood trees and sandalwood oil. The wood is used as a spice, incense ingredients, aromatherapy, fragrance mix, and sangkurkeris (sheath).

In Indonesia, this wood is found in East Nusa Tenggara, particularly on the island of Timor, although it is now found also in Java and Nusa Tenggara islands other.
Sandalwood is a parasitic plant in early life. Kecambahnya need to support the growth of host trees, because the roots themselves are not capable of supporting life. Because this is a prerequisite sandalwood difficult bred or cultivated. [2]
Fragrant sandalwood (Santalum album) is now very rare and very expensive. Wood from the area Mysoram in southern India is generally considered the best quality. In Indonesia, sandalwood from Timor is also greatly appreciated. Instead, aromatherapy and perfume experts using jenggi sandalwood (Santalum spicatum). These tree species different concentrations of the chemicals they contain, and therefore different levels of fragrance too.
Sandalwood is considered as an alternative medicine to bring people closer to God. Base oils of sandalwood, which is very expensive in its pure form, is used primarily for Ayurvedic healing way, and to relieve anxiety.
Mahogany wood is an excellent timber used for the manufacture of MABLE etc.. This kind of wood is rare among us. now that the wood has been protected by the government.
Ulin wood or also called ironwood. wood is very strong on this one as well as iron. The timber can be encountered, or we get from the island of Kalimantan. there a lot of ironwood. The wood is now protected the local government. because the wood is very rare and very difficult to obtain.
Two years sengon's popularity increased. In fact, he was known as a timber class 3. The cause? 'Very severe damage to natural forests. Degradation rate of 2.87 million ha per year, causing forest can no longer be a supplier of timber for industrial raw materials, 'said Ahmad Ridwan Pasaribu, researchers Center for Forest Products Research and Development.
According to Dr. Iskandar Zul Siregar, lecturer at the Faculty of Forestry, Bogor Agricultural University, in 1990 recorded 564 forest concession company with production of 28-million tons. The amount left over 247 companies that produce 11-million tons in 2003. 'Illegal logging can be 4 times more than the total production, "said Iskandar. When the shrinking forest area, on the other side of it, "Wood demand is very high and irreplaceable," said doctoral Forest Genetics and Plant Breeding alumnus Georg-August University, Goettingen, Germany, it is.
When it's people and industries that require wood sengon glance. Sengon wood is not as hard as teak. However, with immersion in salt wolman, sengon wood can last 30-45 years. Wolman salt mixture of 25% sodium fl uorida, disodium hydrogen arsenate 25%, 37.5% of sodium chromate, 12.5% ​​dinitro phenol. Other technologies to strengthen sengon is biocomposites. Is not as strong as teak Sengon mixed with other wood in accordance with the designation.
No wonder if many dikebunkan sengon in various areas such as the Kudat District and the Municipality of Banjar, West Java, Waterford and Banyumas (Central Java), and Pasuruan and Karachi (East Java). Community in droves because mengebunkan sengon relatively short period of 5-10 years of cutting. Compare with the felling of teak Tectona grandisyang reach 25-35 years.
In addition, the 'Management of sengon easy cultivation, compliance is not difficult to grow, versatile wood, and improve soil quality and fertility, "says Yana Sumarna MS, researchers Center for Forest Products Research and Development. It was also submitted Sapari employee-owned PT Waskita work under the Public Works Department, which mengebunkan sengon in Ngadirojo, District Lorok, Pacitan, East Java.
'Raising sengon it easy, no risk is too great, and the market there, "said Sapari who came once a month to see the garden sengon Pacitan. For Sapari mengebunkan sengon is saving for retirement later. Currently sengon 1200 at the height of 450 m asl 3 years old. Two years from now when he's 53 years of retirement, Sapari also harvested.
