High-strength concrete and production process thereof
The invention discloses high-strength concrete and a production process thereof, and belongs to the technical field of concrete. The high-strength concrete is mainly prepared from the following raw materials in parts by weight: 100-105 parts of cement, 185-205 parts of quartz sand, 260-285 parts of broken stone, 10-13 parts of steel slag powder, 2-5 parts of a water reducing agent and 45-55 partsof water. According to the high-strength concrete, the steel slag powder is added, so that the later strength of the concrete can be improved by utilizing active ingredients in the steel slag powder under the condition that the cost of the concrete is relatively low, the permeation resistance of the concrete can be improved, and the air shrinkage value of the concrete can be reduced.
本申请公开了一种高强度混凝土及其生产工艺，属于混凝土技术领域。本申请的高强度混凝土，主要由如下重量份数的原料制成：水泥100‑105份、石英砂185‑205份、碎石260‑285份、钢渣粉10‑13份、减水剂2‑5份、水45‑55份。本申请的高强度混凝土中添加了钢渣粉，能够保证混凝土成本较低的情况下，利用钢渣粉中的活性成分，提高混凝土的后期强度，还可以提高混凝土的抗渗透能力并降低混凝土的干缩值。
