Coarse aggregate HUPC150 high-performance concrete and preparation method thereof
The invention discloses coarse aggregate HUPC150 high-performance concrete and a preparation method thereof, and belongs to the technical field of high-performance concrete materials. Comprising the following raw materials in parts by weight: 200 to 360 parts of cement, 210 to 380 parts of a fine agent material, 260 to 400 parts of coarse aggregate, 60 to 120 parts of water, 5 to 15 parts of an external additive, 50 to 80 parts of silica fume, 100 to 160 parts of microbeads, 70 to 100 parts of steel fibers, 10 to 12 parts of a water reducing agent, 10 to 20 parts of magnesium sulfate and 10 to 15 parts of modified calcium oxide. The high-performance concrete has the advantages that the compressive strength and breaking strength of the high-performance concrete can be improved, the mixing amount of the defoaming agent can be increased, the internal compactness of the material can be effectively increased, the mechanical property, durability and working performance of the concrete can be improved by adding materials such as silica fume and microbeads, and meanwhile, the self-weight of the structure is reduced and the heat insulation performance is improved; the comprehensive performance of the concrete is effectively improved.
本发明公开了一种粗骨料HUPC150高性能混凝土及其制备方法，属于高性能混凝土材料技术领域。包括以下重量份的原料制成：水泥200～360份、细剂料210～380份、粗骨料260～400份、水60～120份、外添加剂5～15份，硅灰50～80份，微珠100～160份，钢纤维70～100份，减水剂10～12份，硫酸镁10～20份，改性氧化钙10～15份，在对钢纤维进行使用的过程中在原钢纤维掺量的基础上适量引入合适规格的长纤维，可以提升高性能混凝土抗压强度和抗折强度，增加消泡剂掺量，有效的增加材料内部的密实度，利用硅灰和微珠等材料的加入，可以改善混凝土的力学性能、耐久性和工作性能，同时减轻结构自重和提高隔热性能，有效的提高混凝土的综合性能。
