content, with sand and fly ash Replace cement

<p>mainly in the following aspects: 1, from raw materials, calcium silicate board and fiber cement pressure board is mainly the difference of calcium silicate board cement content, with sand and fly ash Replace cement. 2, fiber cement pressure board is a physical product, calcium silicate board is a chemical product. 3, fiber cement pressure plate with a press, calcium silicate board without a press; calcium silicate board with </p>
<p>autoclave, fiber cement pressure plate does not. 4, fiber cement pressure plate density higher than calcium silicate board, fiber cement pressure board density above 1.5g / cm3, calcium silicate board density of about 1.2g / cm3. 5, the thickness of fiber cement pressure plate can be done 2.5-100mm, calcium silicate board can not do 4mm below the ultra-thin plate and 30mm thick plate, the general calcium silicate board </p>
<p>manufacturers can only do 6-12mm thickness. 6, the normal production of fiber cement pressure plate color cement, calcium silicate board color is white. Second, how to distinguish between fiber cement board and calcium silicate board 1, count density: Calcium silicate board density is much lower than the fiber cement pressure board, through the weight of the board can calculate its approximate density. 2, to see the </p>
