▎ 摘 要
NOVELTY - Double-faced cavity lightweight high-strength assembled wall comprises a light steel keel and a wall module to form a double-faced cavity structure. The wall sequentially comprises an interface layer, a heat preservation layer, a crack-proof layer and a facing layer. The layers are connected by the base cloth. The insulation layer is made of insulation mortar. The heat preservation layer comprises 70-100 pts. wt. cement, 20-25 pts. wt. emery, 30-40 pts. wt. modified polystyrene, 8-12 pts. wt. basalt short fiber, 4-6 pts. wt. expansion perlite coarse particle, 4-8 pts. wt. sea vegetable powder and 50-80 pts. wt. water. USE - The double-faced cavity lightweight high-strength assembled wall is useful for prefabricated building. ADVANTAGE - The wall is simple, has excellent heat preservation and anti-cracking performance, and can satisfy the high performance requirement of the building materials.
