Shrinkage-compensating self-compacting concrete and preparation method thereof
The invention relates to the technical field of building materials, and particularly discloses shrinkage-compensating self-compacting concrete and a preparation method thereof. The shrinkage-compensating self-compacting concrete is prepared from the following raw materials in parts by weight: 100 to 200 parts of cement, 10 to 40 parts of mineral powder, 300 to 400 parts of coarse aggregate, 150 to 300 parts of fine aggregate, 2 to 10 parts of additive, 10 to 20 parts of expanding agent, 9 to 15 parts of rubber particles, 10 to 25 parts of polypropylene fiber and 50 to 90 parts of water, the expanding agent comprises the following raw materials in parts by weight: 10-20 parts of calcium oxide, 30-40 parts of magnesium oxide, 15-25 parts of zeolite, 5-15 parts of phosphorus slag powder and 10-20 parts of FTC particles. The preparation method comprises the following steps: mixing the raw materials of the expanding agent, and then mixing with other raw materials of the concrete to obtain the concrete. The concrete disclosed by the invention has the advantages of excellent expansion performance and high compressive strength.
本申请涉及建筑材料技术领域，具体公开了一种补偿收缩自密实混凝土及其制备方法。一种补偿收缩自密实混凝土，包括如下重量份原料：水泥100‑200份、矿粉10‑40份、粗骨料300‑400份、细骨料150‑300份、外加剂2‑10份、膨胀剂10‑20份、橡胶颗粒9‑15份、聚丙烯纤维10‑25份、水50‑90份；所述膨胀剂包括如下重量份原料：氧化钙10‑20份、氧化镁30‑40份、沸石15‑25份、磷渣粉5‑15份、FTC颗粒10‑20份；其制备方法为：先将膨胀剂原料混合，再与混凝土的其他原料混合，得到混凝土。本申请的混凝土其具有膨胀性能优越，抗压强度高的优点。
