Anti-crack and anti-corrosion concrete and production method thereof
The invention relates to the technical field of concrete production, and particularly discloses anti-crack and anti-corrosion concrete and a production method thereof. The anti-crack and anti-corrosion concrete is prepared from the following raw material components in parts by weight: 250 to 320 parts of sulphoaluminate cement, 700 to 850 parts of gravel, 350 to 450 parts of sand, 110 to 190 parts of kaolin, 60 to 130 parts of blast furnace slag, 20 to 50 parts of feldspar powder, 20 to 40 parts of composite fiber, 8 to 20 parts of corrosion inhibitor and 150 to 200 parts of water, the composite fibers comprise polypropylene fibers, glass fibers and carbon fibers; the corrosion inhibitor is calcium ammonium nitrate coated with sodium dioctyl sulfosuccinate and hydroxy propyl distarch phosphate. The composite fibers and the corrosion inhibitor are added into the preparation raw materials of the concrete, so that the corrosion speed of chloride ions is slowed down, and the cracking resistance and corrosion resistance of the concrete are improved.
本申请涉及混凝土生产技术领域，具体公开了一种抗裂抗腐蚀混凝土及其生产方法。一种抗裂抗腐蚀混凝土，按重量份计，混凝土的制备原料包括如下组分：硫铝酸盐水泥250‑320份、碎石700‑850份、砂350‑450份、高岭土110‑190份、高炉渣60‑130份、长石粉20‑50份、复合纤维20‑40份、缓蚀剂8‑20份和水150‑200份；复合纤维包括聚丙烯纤维、玻璃纤维和碳纤维；缓蚀剂为琥珀酸二异辛酯磺酸钠和羟丙基二淀粉磷酸酯包覆的硝酸铵钙。本申请通过在混凝土的制备原料中添加了复合纤维和缓蚀剂，减缓氯离子的侵蚀速度，提升混凝土的抗开裂性能和抗腐蚀性能。
