Aerated concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly provides aerated concrete which is prepared from the following components in parts by mass: 30 to 60 parts of mineralized cementing material, 10 to 30 parts of cement, 15 to 30 parts of fly ash, 20 to 40 parts of lime, 3 to 6 parts of dihydrate gypsum, 0.05 to 0.15 part of gas forming agent, 10 to 20 parts of mixing water, 0.01 to 1 part of foam stabilizer and 0.1 to 2 parts of water reducing agent. According to the aerated concrete provided by the invention, the mineralized cementing material is selected as a main base material, and the use amount of cement is greatly saved under the condition of the same strength by utilizing the air hardening principle and excellent mechanical property of the mineralized cementing material, so that the consumption of a certain scale of high recarburization main materials can be saved, and the problem of carbon emission caused by industrial production can be solved. The invention further provides a preparation method of the aerated concrete, CO2 discharged by industrial production can be directly utilized, pressurization is not needed in the curing process, the technological process is simple, the time needed for increasing the mechanical property of the aerated concrete is effectively shortened, the curing energy consumption is reduced, and remarkable environmental and economic benefits are achieved.
本发明属于建筑材料技术领域，具体提供了一种加气混凝土，以质量分数计，包括：30‑60份矿化胶凝材料，10‑30份水泥，15‑30份粉煤灰，20‑40份石灰，3‑6份二水石膏，0.05‑0.15份发气剂，10‑20份拌和水，0.01‑1份稳泡剂，0.1‑2份减水剂。本发明提供的这种加气混凝土选用矿化胶凝材料作为主要基材，利用其气硬性原理及优异的力学性能，在相同强度条件下大幅节省了水泥用量，既可节省一定规模的高增碳主材的消耗，又能解决工业生产带来的碳排放问题。本发明还提供了上述加气混凝土的制备方法，可直接利用工业生产排出的CO2，养护过程无需加压，工艺流程简单，有效缩短加气混凝土力学性能增长所需的时间，降低养护能耗，具有显著的环境和经济效益。
