The main material is autoclaved lime sand brick sand (about 90%) and lime (approximately 10%) of ingredients sand-lime brick, brick and some color materials sand-lime brick, through stock preparation, compression molding, autoclave curing three phase steel. There are solid and hollow brick two kinds. ① durability frost resistance: refers to the ability to resist repeated freezing and thawing brick effect. Autoclaved sand-lime brick production if required to meet product standards sand-lime brick size, can withstand frost resistance test sand-lime brick, sand-lime brick autoclaved frost resistance related to its own strength, high strength by frost resistance . ② Water resistance: after effects include dry and wet cycles and changes in their strength when long-term immersion in water, the wet-dry cycle effects or long-term water autoclaved sand-lime brick compressive strength are on the rise.
