Polypropylene fiber aerated concrete block and preparation method thereof
The invention discloses a polypropylene fiber aerated concrete block and a preparation method thereof, and relates to the technical field of building materials. The polypropylene fiber aerated concrete block comprises: 20-30 parts of cement; 60-120 parts of lime; 200-250 parts of fly ash; 10-15 parts of gypsum; 0.5-1 part of aluminum powder; 0.1-0.5 part of a polypropylene fiber; 5-10 parts of bentonite; 300-500 parts of water. The preparation method comprises the following steps: S1, uniformly mixing the cement, the lime, the fly ash, the gypsum, the aluminum powder, the polypropylene fibersand the bentonite; S2, adding water and aluminum powder into the mixture obtained in the step S1, uniformly stirring, pouring the slurry into a mold, standing the mold in an environment with the temperature of 22 +/-2 DEG C and the humidity of 60 +/-10% for 3-4 hours, demolding, and cutting according to requirements; and S3, putting the cut building block into a 60-80 DEG C autoclave, carrying outsteam curing for 10-12 hours, cooling to room temperature, and standing for 7 days in a standard environment to obtain the building block. The polypropylene fiber aerated concrete block prepared by the invention has the advantages of high mechanical strength and light weight.
本申请公开了一种聚丙烯纤维加气混凝土砌块及其制备方法，涉及建筑材料技术领域。该聚丙烯纤维加气混凝土砌块包括：水泥20‑30份；石灰60‑120份；粉煤灰200‑250份；石膏10‑15份；铝粉0.5‑1份；聚丙烯纤维0.1‑0.5份；膨润土5‑10份；水300‑500份。其制备步骤为：S1，将水泥、石灰、粉煤灰、石膏、铝粉、聚丙烯纤维和膨润土混合均匀；S2，步骤S1得到的混合物中加入水和铝粉，搅拌均匀后，将浆料倒入模具中，将模具于22±2℃、湿度60±10%环境下静置3‑4h，脱模并按要求切割；S3，将切割后的砌块置于60‑80℃蒸压釜中进行蒸汽养护10‑12h，然后降至室温，并于标准环境下静置7d，即得。本申请制备的聚丙烯纤维加气混凝土砌块具有机械强度高、质量轻便的优点。
