Comparison of Brick and Hebel (lightweight concrete)

Today the building materials of the replacement brick beragam.Mulai increasingly using Hebel or changed using the cover plate floors are made from lightweight and to the roof no longer use wood as a horse â € "a horse or for battens and usuknya, but the current trend of people using a steel ringa as a substitute for wood.

Aluminum pastes used in the mixture, in addition to functioning as a developer he was instrumental in influencing the hardness of concrete. Aluminum paste volume is around 5-8 percent of the dough is made, depending on the desired density. The dough is then aerated concrete is cut to size.

As for brick brick brick types consists of clay or loam, sand lime bricks, mortar and brick. Meanwhile, in terms of manufacture, there is a conventional red bricks and brick press.

When viewed in terms of price for a single brick ranges from USD 375, - / buahnya.Untuk Hebel Rp 650.000, - / m3. So that the average unit price â € "average of Rp. 6500, - / fruit. Thus, in a large brick 1m2 to cost USD 375, - x 85 = Rp. 31 875, - (outside of the speci). And to Hebel in 1m2 is Rp. 6500, - x 8.5 = Rp. 55 250, - (outside of the speci). Indeed for Hebel falling prices higher. But in terms of weight for structured, Hebel lighter and faster process.
