Anti-cracking concrete and preparation method thereof
The invention discloses anti-cracking concrete and a preparation method thereof, and relates to the technical field of building materials. The concrete is prepared from the following raw materials in parts by weight: 30-40 parts of cement, 8-10 parts of slag powder, 30-50 parts of broken stone, 30-50 parts of a construction waste regenerated material, 5-8 parts of fly ash, 3-5 parts of silica fume, 15-25 parts of quartz sand, 1-3 parts of an additive, 35-45 parts of water, 1-3 parts of amino-terminated water-soluble hyperbranched polyamide, 2-4 parts of waste plant polysaccharide and 1-3 parts of 9, 10-di-tert-butyl-4-methylphenol. 1 to 2 parts of 9, 9-bis (4-epoxypropyl oxyphenyl) fluorene, and 1 to 2 parts of hyperbranched polyurethane containing ammonium sulfonate. The anti-cracking concrete disclosed by the invention is high in compressive strength, remarkable in anti-cracking and anti-seepage effects and long in service life.
本发明公开了一种防开裂混凝土及其制备方法，涉及建筑材料技术领域，是由如下按重量份计的如下原料制成：水泥30‑40份、矿渣粉8‑10份、碎石30‑50份、建筑垃圾再生料30‑50份、粉煤灰5‑8份、硅灰3‑5份、石英砂15‑25份、外加剂1‑3份、水35‑45份、端氨基水溶性超支化聚酰胺1‑3份、废弃植物多糖2‑4份、9,9‑双(4‑环氧丙基氧代苯基)芴1‑2份、含磺酸铵盐的超支化聚氨酯1‑2份。本发明公开的防开裂混凝土抗压强度大，防裂抗渗效果显著，使用寿命长。
