Phosphogypsum concrete gelling material for indoor terrace
The invention belongs to an ardealite-based cementing material for concrete, and particularly relates to an ardealite concrete cementing material for indoor terraces, which is prepared from the following raw materials in parts by weight: 90 to 95 parts of mixed-phase gypsum powder, 1 to 2 parts of fly ash, 1 to 2 parts of ash calcium, 0.012 to 0.016 part of water reducing agent, 0.05 to 0.12 part of retarder, 3 to 7 parts of Portland cement clinker powder, 0.1 to 0.2 part of cellulose, 0.0001 to 0.0003 part of water repellent and 0.01 to 0.025 part of calcium formate. The ardealite concrete gelling material for the indoor terrace has excellent mechanical properties; through tests, the water-gel strength of the mixed use of the gelling material and sand/gravel (the ratio of the gelling material to the aggregate is 1: 4) can reach 25-30 MPa, and the method can be widely applied to indoor terrace engineering with 25-30 MPa.
本发明属于混凝土用磷石膏基胶凝材料，尤其涉及一种室内地坪用磷石膏砼胶凝料，由以下重量份的原料制成：混合相石膏粉90～95份、粉煤灰1～2份、灰钙1～2份、减水剂0.012～0.016份、缓凝剂0.05～0.12份、硅酸盐水泥熟料粉3～7份、纤维素0.1％～0.2％份、憎水剂0.0001～0.0003份、甲酸钙0.01～0.025份，本发明的室内地坪用磷石膏砼胶凝料具有优异的力学性能；通过试验，本方法名的胶凝料与砂/碎石混合使用(胶凝料比集料＝1:4)的水胶强度可达25～30MPa，可以广泛应用要求在25～30MPa室内地坪工程。
