High-strength concrete and preparation method thereof
The invention discloses high-strength concrete and a preparation method thereof. The high-strength concrete is prepared from the following raw materials in parts by weight: 230 to 440 parts of cement, 40 to 60 parts of fly ash, 600 to 900 parts of medium sand, 1000 to 1100 parts of stone, 6 to 11 parts of concrete admixture, 50 to 70 parts of mineral powder, 10 to 20 parts of glass fiber, 10 to 20 parts of nano silicon dioxide, 30 to 60 parts of bauxite and 140 to 180 parts of water, the compactness of the prepared concrete can be better improved by selecting all the raw materials and the dosage, meanwhile, the mechanical property of the prepared concrete can be better improved by further limiting the particle size of all the raw materials, and the application field of the concrete is expanded.
本发明公开了一种高强度的混凝土及其制备方法，所述高强度的混凝土包括如下重量份的原料：水泥230～440份、粉煤灰40～60份、中砂600～900份、石子1000～1100份、混凝土外加剂6～11份、矿粉50～70份、玻璃纤维10～20份、纳米二氧化硅10～20份、铝矾土30～60份和水140～180份；本发明通过对各原料和用量的选择，能够更好的提高制备混凝土的密实度，同时，通过各原料粒径的进一步限定，能够更好的改善制备混凝土的力学性能，扩展了混凝土的应用领域。
