High-strength concrete with pumice waste residues as aggregate and preparation method of high-strength concrete
The invention relates to high-strength concrete with pumice waste residues as aggregate and a preparation method of the high-strength concrete. The concrete comprises the following raw materials in parts by weight: 280 to 340 parts of cement, 94 to 98 parts of fly ash, 1100 to 1200 parts of pumice waste residue, 45 to 55 parts of steel fiber, 100 to 120 parts of alkali-resistant glass fiber, 250 to 300 parts of water, 0.8 to 1.2 parts of glucose, 0.5 to 1 part of cellulose ether, 3 to 5 parts of a water reducing agent, 1 to 2 parts of a thickening agent and 55 to 63 parts of expanded volcanic rock particles. The pumice waste residues in the concrete can flow along with slurry, the fluidity of the concrete is improved, floating of the pumice waste residues is prevented, no treatment needs to be conducted on the surfaces of the pumice waste residues, particle size screening does not need to be conducted on the pumice waste residues, pumice waste residues can be used directly, and meanwhile, the strength, tensile strength, fracture resistance and crack resistance of the recycled concrete are improved.
本发明涉及一种以浮石废渣为骨料的高强度混凝土及其制备方法，包括以下步骤：包括以下重量份数配比的原料：水泥280‑340份、粉煤灰94‑98份、浮石废渣1100‑1200份、钢纤维45‑55份、耐碱玻璃纤维100‑120份、水250‑300份、葡萄糖0.8‑1.2、纤维素醚类0.5‑1份、减水剂3‑5份、增稠剂1‑2份、膨化的火山岩颗粒55‑63份，本发明使混凝土中浮石废渣能够跟随浆体的流动，改善了混凝土流动性，阻止浮石废渣的上浮，需要对浮石废渣的表面进行任何处理，也不需要对浮石废渣进行粒度筛选，可以实现对浮石废渣的直接应用，同时提高再生混凝土的强度、抗拉、抗折和抗裂性性能。
