Environment-friendly building municipal engineering foam concrete and preparation method thereof
The invention discloses environment-friendly building municipal engineering foam concrete and a preparation method thereof, and relates to the technical field of building materials. Based on the problems of low compressive strength, extremely easy shrinkage cracking and not high overall strength of foam concrete, the technical scheme of the invention is that the environment-friendly building municipal engineering foam concrete comprises the following raw materials in parts by mass: 580-680 parts of cementing material cement, 150-250 parts of fly ash, 50-70 parts of a fiber filler, 200-280 parts of water, 900-1000 parts of dry sand, 35-45 parts of aluminum powder, 13.5-15 parts of a water reducing agent, 13.5-15 parts of a foaming agent and 13.5-15 parts of an early drought agent. Accordingto the invention, the cementing material cement, the fly ash, the fiber filler, the water, the dry sand, the aluminum powder, the water reducing agent, the foaming agent and the early drought agent are mixed according to a certain ratio, and are casted into concrete, so that the obtained concrete has advantages of good compressive strength, no shrinkage cracking, high in overall strength, long service cycle, convenient curing, good thermal-insulation performance, small heat conductivity coefficient and good thermal-insulation effect.
本发明公开了一种环保型建筑市政工程用泡沫混凝土及其制备方法，涉及建筑材料技术领域，针对泡沫混凝土抗压强度不高，同时极易收缩开裂，整体强度不高的问题，现提出如下方案，其包括如下质量份数的原料：胶凝材料水泥580‑680份、粉煤灰150‑250份、纤维填料50‑70份、水200‑280份、干砂900‑1000份、铝粉35‑45份、减水剂13.5‑15重量份、发泡剂13.5‑15重量份、早旱剂13.5‑15重量份，本发明通过将胶凝材料水泥、粉煤灰、纤维填料、水、干砂、铝粉、减水剂、发泡剂以及早旱剂按照比例进行配比混合，然后浇筑呈混凝土，其具有良好的抗压强度，同时不用收缩开裂，整体强度高，使用周期长，养护便捷，同时具有良好的隔热性能，导热系数小，保温效果好。
