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.
