High-strength foam concrete and preparation method thereof
The invention relates to the technical field of foam concrete, and discloses high-strength foam concrete and a preparation method thereof, and the high-strength foam concrete comprises the following raw materials by weight: 350-450 parts of cement, 80-120 parts of wollastonite, 100-150 parts of sand, 280-320 parts of water, 0.01-0.03 part of an expanding agent, 0.3-0.5 part of a foaming agent, 10 kg/m < 3 > of nano-silica, and 1 kg/m < 3 > of cellulose fiber. According to the high-strength foam concrete, the expanding agent, the foaming agent, the nano silicon dioxide and the cellulose fibers are added into the components of the high-strength foam concrete, and the nano silicon dioxide is mainly used for filling micropores and cracks in the foam concrete, so that the compactness and the strength of the foam concrete are improved; the cellulose fiber is mainly used for enhancing the tensile property and the crack resistance of the foam concrete, and also can improve the toughness and the durability of the foam concrete; under the combined action of the expanding agent, the foaming agent, the nano silicon dioxide and the cellulosic fibers, the strength and the mechanical property of the foam concrete are greatly improved, and the application field of the foam concrete is expanded.
本发明涉及泡沫混凝土技术领域，且公开了一种高强度泡沫混凝土及其制备方法，包括以下重量份数配比的原料：水泥350‑450份、硅灰石80‑120份、沙子100‑150份、水280‑320份、膨胀剂0.01‑0.03份、泡沫剂0.3‑0.5份、纳米二氧化硅10kg/m3、纤维素纤维1kg/m3。该高强度泡沫混凝土，通过在高强度泡沫混凝土的组份中添加膨胀剂、泡沫剂、纳米二氧化硅和纤维素纤维，纳米二氧化硅主要用于填充泡沫混凝土中的微孔和裂缝，提高泡沫混凝土的密实性和强度；纤维素纤维主要用于增强泡沫混凝土的抗拉性能和抗裂性能，同时也能够提高泡沫混凝土的韧性和耐久性；在膨胀剂、泡沫剂、纳米二氧化硅和纤维素纤维的共同作用下，泡沫混凝土的强度和力学性能都有了极大的提高，扩大了泡沫混凝土的应用领域。
