High-strength concrete with strong durability and good workability, and preparation method thereof
The invention belongs to the field of concrete, and discloses a high-strength concrete with a high durability and good workability, and a preparation method thereof. The high-strength concrete is prepared from, by weight, 140 to 160 parts of water, 650 to 730 parts of cement, 23 to 33 parts of silica fume, 480 to 510 parts of steel slag sand, 390 to 405 parts of natural river sand, 780 to 840 parts of granite macadam and 7.5 to 15.1 parts of a polycarboxylic acid type water reducing agent. According to the high-strength concrete, the steel slag sand is adopted to partially replace natural river sand, the situation of shortage of the natural river sand is relieved, and the high-strength concrete has the advantages of high strength, high fluidity, high segregation resistance, high gap passing ability and high durability.
本发明属于混凝土领域，公开了一种耐久性强、和易性好的高强混凝土及其制备方法。所述高强混凝土中包括以下重量份数的原料组分：水140‑160份、水泥650‑730份、硅灰23‑33份、钢渣砂480‑510份、天然河沙390‑405份、花岗岩碎石780‑840份、聚羧酸型减水剂7.5‑15.1份。该高强混凝土中采用钢渣砂以部分取代天然河沙的使用，缓解了天然河砂短缺的情况，且具有高强度、高流动性、高抗离析性、高间隙通过性及高耐久性的优势。
