Anti-freezing autoclaved aerated building block and preparation method thereof
The invention relates to the technical field of concrete blocks, and particularly discloses an anti-freezing autoclaved aerated block and a preparation method thereof. The anti-freezing autoclaved aerated building block is prepared from, by weight, 2600 to 2800 parts of a filler; 140 to 150 parts of gypsum; 240 to 260 parts of quick lime; 230 to 250 parts of cement; 2 to 3 parts of a foaming agent; 3 to 5 parts of a water reducing agent; 20 to 30 parts of water; and 5 to 10 parts of an anti-freezing agent. The anti-freezing agent is mainly composed of an acrylic emulsion, hollow glass beads and rubber powder. The anti-freezing autoclaved aerated building block disclosed by the invention has excellent anti-freezing performance, can work for a long time under a low-temperature condition, does not generate cracks, and is durable.
本申请涉及混凝土砌块技术领域，具体公开了一种抗冻的蒸压加气砌块及其制备方法。抗冻的蒸压加气砌块按重量份数计算，包括如下组分：填料2600‑2800份；石膏140‑150份；生石灰240‑260份；水泥230‑250份；发泡剂2‑3份；减水剂3‑5份；水20‑30份；防冻剂5‑10份；防冻剂主要由丙烯酸乳液、空心玻璃微珠、橡胶粉组成。本申请的抗冻的蒸压加气砌块具有优良的抗冻性能，可在低温条件下长期工作，无裂纹产生，经久耐用。
