Foam concrete formula and preparation process thereof
The invention discloses a foam concrete formula and a preparation process thereof. The foam concrete is prepared from the following components in parts by weight: 5 to 10 parts of Portland cement clinker, 10 to 20 parts of fly ash, 10 to 20 parts of stone powder or mineral powder or construction waste powder, 2 to 3 parts of acrylic acid, 7 to 9 parts of water, 0.1 to 0.2 part of a composite foaming agent, 1.5 to 3 parts of an exciting agent, 0.2 to 0.4 part of a thickening agent, 4 to 5 parts of aggregate, 6 to 10 parts of silica fume, 2 to 10 parts of calcium chloride, 1 to 5 parts of activated carbon and 2 to 5 parts of foam. According to the foam concrete disclosed by the invention, the silica fume and the calcium chloride are added in the preparation process of the foam concrete, so that the setting and hardening time of the foam concrete can be effectively shortened, meanwhile, the activated carbon is added in the preparation process of the foam concrete, so that water molecules generated during fusion can be adsorbed in the fusion preparation process; the water cement ratio and free moisture in a concrete mixture are reduced, and the hardness of the set and hardened foam concrete is improved.
本发明公开了一种泡沫混凝土配方及其制备工艺，该泡沫混凝土的组分及重量成分组成包括：硅酸盐水泥熟料5‑10份、粉煤灰10‑20份、石粉或矿粉或建筑垃圾粉10‑20份、丙烯酸2‑3份、水7‑9份、复合起泡剂0.1‑0.2份、激发剂1.5‑3份、增稠剂0.2‑0.4份、骨料4‑5份，硅灰6‑10份、氯化钙2‑10份、活性炭1‑5份、泡沫2‑5份。本发明的泡沫混凝土，在泡沫混凝土制备过程中加入硅灰以及氯化钙能够有效的缩短泡沫混凝土的凝结硬化时间，同时在制备泡沫混凝土的过程中加入活性炭，能够在融合制备过程对融合时所产生的水分子进行吸附，以降低水灰比和混凝土拌合物中游离水分，达到其提高凝结硬化后泡沫混凝土的硬度。
