Gypsum composition, block and steel skeleton lightweight high strength anti-cracking gypsum plank
The invention discloses a gypsum composition. By pouring the gypsum composition in a die and conducting hardening, the block can be molded, and by pouring the gypsum composition in the die loaded with a steel wire mesh or glass fiber mesh prefabricated three-dimensional steel skeleton and conducting hardening, a steel skeleton steel wire mesh (or glass fiber mesh) lightweight high strength anti-cracking gypsum board, especially a plank can be molded. The gypsum composition includes: semi-hydrated gypsum, Portland cement, fly ash, elastomer powder, a water reducing agent, a foaming agent and water. The composition also include: micro silicon powder, slag powder, and/or water granulated slag powder, and an antifreezing agent. The dosage of water should makes the wet unit weight of silt slurry in the range of 1.4-1.85 ton/cubic meter. The three-dimensional steel skeleton is a hexahedral steel skeleton, and also can be an irregular part with window frame or door frame or with a part of window frame or door frame.
