Fused silica brick has better thermal shock resistance, much lower thermal expansion, and can be used to do hot repair. Fused Silica Brick for Hot Repair of Coke Oven is similar to general silica brick, but it has better thermal shock resistance. The property of fused silica brick is similar to general silica brick, but it has better thermal shock resistance, much lower thermal expansion and it can stand suddenly change of temperature. It also can be heated in very short time after buildup and do not need to calculate thermal expansion. So we can directly use its cold size for masonry. Put on wooden pallets, tightened with iron stripes, covered with plastic bag, warped with film, shipped in pallet by container. Do corner protection and other measures to avoid products from breaking. And these packages should be under ISPM standard.
The products produced by the DHC to meet minimum standards for the Bloc lightweight concrete is made from a mixture of cement, fine aggregate, or foaming agent used for the gas bearing structure, bearing the thermal insulation in buildings under TCXDVN 316-2004 and are checked by TCXDVN 317-2004 (for foam concrete) and ISO 7959:2008 - applied to the blocks air, solidifying the general conditions apply (referred to as AAC), used for construction.
