Low-shrinkage low-viscosity high-strength concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses low-shrinkage low-viscosity high-strength concrete and a preparation method thereof. The low-shrinkage low-viscosity high-strength concrete is prepared from the following raw materials: 200 to 300 parts of cement, 100 to 150 parts of mineral powder, 80 to 150 parts of fly ash, 60 to 100 parts of silica fume, 30 to 50 parts of heavy calcium powder, 80 to 100 parts of glass beads, 500 to 700 parts of modified porous basalt, 500 to 700 parts of granite gravel, 10 to 15 parts of a water reducing agent, 20 to 30 parts of concrete fiber and 150 to 180 parts of water. The preparation method of the porous basalt broken stone comprises the following modification steps: S1, soaking the porous basalt broken stone in paraffin for 2-10 hours; s2, taking out the porous basaltic gravels, and rapidly cooling; s3, a wrapping layer is arranged on the outer surface of the porous basaltic gravel, and the modified porous basaltic gravel is obtained. The prepared concrete has the advantages of being high in strength, good in fluidity and high in anti-cracking performance.
本申请涉及建筑材料领域，具体公开了一种低收缩低粘度高强混凝土及其制备方法。一种低收缩低粘度高强混凝土，包括以下原料：水泥200‑300份、矿粉100‑150份、粉煤灰80‑150份、硅灰60‑100份、重钙粉30‑50份、玻璃微珠80‑100份、改性多孔玄武碎石500‑700份、花岗岩碎石500‑700份、减水剂10‑15份、混凝土纤维20‑30份、水150‑180份；多孔玄武碎石包括以下改性步骤：S1：将多孔玄武碎石在石蜡中浸泡2‑10h；S2：捞出多孔玄武碎石，快速冷却；S3：在多孔玄武碎石外表设置包裹层，得到改性多孔玄武碎石。本申请制备的混凝土强度高，流动性好并且抗开裂性能高的优点。
