Silica Content In Crushed Quartz Sand. To make calcium silie bricks, silica sand is mixed with high calcium lime at a sandlime ratio of 10 or mix is then compressed into moulds and autoclaved at about 170c 340f for several gel, similar to the calcium silie hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.

than fraction – mm of the same silica sand type. Thiel et al. [11] investigated the effect of various factors like grain size, grain shape, grain size distribution, chemical composition and density on the thermal expansion of silica sands. They studied four individual size ranges of a silica sand and found correlation indiing that the finer the grain size the lower the peak ...

So should filter sand – mm not be installed directly on a support gravel with mm, because the pore volume is greater than the smallest grain. In such a case, mm or 2 mm have to be installed as an intermediate layer. Regarding the density, the expansion behavior is important (how far the bed expands at the same flow pressure).
