Efficient anti-carbonization concrete and preparation method thereof
The invention belongs to the technical field of concrete, and particularly relates to efficient anti-carbonization concrete and a preparation method thereof. The high-efficiency anti-carbonization concrete comprises the following components in parts by weight: 300-400 parts of cement, 30-50 parts of fly ash, 30-80 parts of mineral powder, 300-500 parts of medium sand, 600-800 parts of broken stone, 50-100 parts of reinforced fibers, 20-30 parts of an anti-carbonization agent, 10-30 parts of a water reducing agent, 20-30 parts of a reinforcing agent and 100-200 parts of water, the broken stone is continuous graded broken stone, and the anti-carbonization agent is obtained by mixing activated carbon and hydrotalcite according to a mass ratio of (6-8): (2-4). The reinforcing agent is obtained by mixing water-absorbent resin and fumed silica at a high speed. The concrete with good carbonization resistance and compressive strength is obtained by taking II-type Portland cement, fly ash, mineral powder, medium sand and gravel as base materials, additionally adding reinforcing fibers and combining with an anti-carbonization agent, a water reducing agent and a reinforcing agent.
本发明属于混凝土技术领域，具体涉及一种高效抗碳化混凝土及其制备方法。所述高效抗碳化混凝土，包括以下重量份数的组分：水泥300～400份、粉煤灰30～50份、矿粉30～80份、中砂300～500份、碎石600～800份、增强纤维50～100份、抗碳化剂20～30份、减水剂10～30份、增强剂20～30份、水100～200份，碎石为反击破连续级配碎石，抗碳化剂为活性炭和水滑石按照6～8:2～4的质量比混合得到，增强剂是由吸水树脂和气相二氧化硅高速混合得到。以Ⅱ型硅酸盐水泥、粉煤灰、矿粉、中砂、碎石为基料，外加增强纤维，再结合抗碳化剂、减水剂、增强剂，得到具有良好抗碳化能力和抗压强度的混凝土。
