Foam concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses foam concrete and a preparation method thereof. The foam concrete is prepared from the following raw materials in parts by weight: 35 to 45 parts of water, 65 to 85 parts of cement, 30 to 40 parts of fly ash, 1 to 2 parts of foaming agent, 0.9 to 1.2 parts of water reducing agent, 5 to 10 parts of butadiene styrene rubber emulsion and 5 to 15 parts of reinforcing filler, the reinforcing filler is prepared from the following raw materials: graphene, ethanol and dimethyl vinyl ethyoxyl silane. According to the preparation method, ethyl alcohol is used as a solvent, and the dimethyl vinyl ethoxy silane is used for modifying the graphene, so that the graphene can be uniformly dispersed in a system; the styrene butadiene rubber emulsion can form a net-shaped structure after water loss, cement base materials are mutually connected, dimethyl vinyl ethoxy silane can promote formation of the net-shaped structure, and then the compressive strength of the prepared foam concrete is improved by utilizing the hardness of graphene.
本申请涉及建筑材料的技术领域，具体公开了一种泡沫混凝土及其制备方法。一种泡沫混凝土，所述混凝土的原料包括如下重量份的组分：水35~45份、水泥65~85份、粉煤灰30~40份、发泡剂1~2份、减水剂0.9~1.2份、丁苯橡胶乳液5~10份、增强填料5~15份；所述增强填料的原料包括：石墨烯、乙醇、二甲基乙烯基乙氧基硅烷。本申请中乙醇作溶剂，利用二甲基乙烯基乙氧基硅烷对石墨烯进行改性，使得石墨烯可以均匀分散在体系中；丁苯橡胶乳液在失水后会形成网状结构，将水泥基材之间相互连接，二甲基乙烯基乙氧基硅烷可以促进网状结构的形成，再利用石墨烯的硬度，从而提高了制得泡沫混凝土的抗压强度。
