Silica sand for the manufacture of light brick.
Mild brick AAC is a Material that is made of silica sand, cement, lime and water is made with a high vapor pressure. Material manufacturing process begins with the process of mixing raw materials. After that, the raw ingredients of dough is placed into a tool called autoclaved. In this instrument, the dough is given a vapor pressure of water up to a temperature of about 200 degrees centigrade. Therefore, the process of using autoclaved materials then this is referred to as autoclaved aerated concrete
.
With a vapor pressure of this raw material, limestone and silica sand will react. This reaction results
produce pores which form the air. The pores of this is what makes this material becomes light. According to calculations, the concrete masonry has a weight of approximately normal type 650 kg/m3. Heavy type that is smaller than the weight of the water creating this material type can downloadgapung on the water. Although porous, of lightweight concrete aeration is not like a sponge.
That is, keteika is exposed to water, the water will not sink or seeping into it. Low water absorption because each pore that there are not interconnected with the others.
