High-strength concrete and production process thereof
The invention discloses high-strength concrete and a production process thereof. The high-strength concrete is prepared from the following raw materials in parts by weight: 15-25 parts of Portland cement, 10-15 parts of granite, 5-15 parts of fly ash, 10-15 parts of lime, 4-8 parts of a water reducing agent, 20-40 parts of sand, 5-10 parts of coarse aggregate, 10-15 parts of fine aggregate, 0.1-0.5 part of carbon nano fibers, 1-3 parts of basalt fibers, 0.1-0.5 part of glass fibers and 30-50 parts of water. The coarse aggregate and the fine aggregate are both prepared from waste concrete through a crushing and grinding integrated machine, the particle size of the coarse aggregate is 5-10 mm, and the particle size of the fine aggregate is 1-5 mm. Recycling of waste concrete is achieved, andthe strength of the prepared concrete can meet the strength grade requirement of high-strength concrete.
本发明公开了高强度混凝土及其生产工艺，该高强度混凝土包含如下重量份计的原料：硅酸盐水泥15‑25份、花岗岩10‑15份、粉煤灰5‑15份、石灰10‑15份、减水剂4‑8份、砂20‑40份、粗骨料5‑10份、细骨料10‑15份、纳米碳纤维0.1‑0.5份、玄武岩纤维1‑3份、玻璃纤维0.1‑0.5份、水30‑50份；所述粗骨料和细骨料均由废弃混凝土经粉碎研磨一体机制得，且所述粗骨料的粒径为5‑10mm，所述细骨料的粒径为1‑5mm。本发明实现了废弃混凝土的再利用，且制备的混凝土的强度能够满足高强度混凝土的强度等级要求。
