Self-insulation ALC (autoclaved lightweight concrete) aerated concrete wallboard and preparation method thereof
The invention relates to a self-insulation ALC aerated concrete wallboard and a preparation method thereof. The concrete wallboard is prepared from the following raw materials in parts by weight: 25 parts of fly ash, 250 parts of lime, 250 parts of cement, 25 parts of desulfurized gypsum, 100 parts of lightweight aggregate, 20 parts of silica fume, 2 parts of a water reducing agent, 2 parts of water glass, 1 part of aluminum sulfate, 0.55 part of aluminum powder, 0.5 part of triethanolamine and 100 parts of water. The self-heat-preservation ALC aerated concrete wallboard is reasonable in formula and convenient to construct, the strength of the processed wallboard can reach 5-10 MPa or above, the heat conductivity coefficient can reach 0.062-0.12 W/M.K, the wallboard has excellent heat preservation performance, a heat preservation board does not need to be additionally arranged in the specific construction process, and the construction and material cost is saved.
本发明涉及一种自保温ALC加气混凝土墙板及其制备方法，所述混凝土墙板由以下重量份数的原料制成：粉煤灰25，石灰250，水泥250，脱硫石膏25，轻骨料100，硅灰20，减水剂2，水玻璃2，硫酸铝1，铝粉0.55，三乙醇胺0.5，水100。本发明的自保温ALC加气混凝土墙板配方合理，施工方便，所加工的墙板强度可达5‑10兆帕以上，导热系数可达0.062‑0.12W/M.K，具有优良的保温性能，具体施工时无需加装保温板，节省了施工与材料成本。
