High-strength and high-crack-resistance hydraulic anti-abrasion concrete and preparation method thereof
The invention relates to high-strength and high-crack-resistance hydraulic anti-abrasion concrete and a preparation method thereof, and the high-strength and high-crack-resistance hydraulic anti-abrasion concrete is prepared from the following raw materials based on the weight of concrete per cubic meter: 125-138 kg/m < 3 > of water, 272-315 kg/m < 3 > of cement, 68.1-78.9 kg/m < 3 > of fly ash, 0.9 kg/m < 3 > of fiber, 27.3-28.6 kg/m < 3 > of silicon powder, 738-764 kg/m < 3 > of fine aggregate, 1137-1178 kg/m < 3 > of coarse aggregate, 2.94-4.73 kg/m < 3 > of a water reducing agent and 0.0257-0.0591 kg/m < 3 > of an air entraining agent. The preparation method comprises the following steps: sequentially adding the coarse aggregate, the cement, the fly ash, the silicon powder, the fine aggregate and the fiber into a stirrer, uniformly stirring for 60-80 seconds, adding the water reducing agent and the air entraining agent into the mixing water, uniformly mixing, slowly adding the mixed solution into the mixture within 10 seconds, and fully mixing and stirring for 90-120 seconds to obtain the high-strength and high-crack-resistance hydraulic anti-abrasion concrete. The concrete has the advantages of being high in strength, excellent in abrasion resistance, good in crack resistance and the like, and the construction cost and the later operation and maintenance cost of enterprises are greatly reduced.
本发明涉及一种高强高抗裂水工抗冲磨混凝土及其制备方法，其原材料占比以每方混凝土重量来计，包括以下组分的原材料：水125～138kg/m3、水泥272～315kg/m3、粉煤灰68.1～78.9kg/m3、纤维0.9kg/m3、硅粉27.3～28.6kg/m3、细骨料738～764kg/m3、粗骨料1137～1178kg/m3、减水剂2.94～4.73kg/m3、引气剂0.0257～0.0591kg/m3；先将粗骨料、水泥、粉煤灰、硅粉、细骨料、纤维，依次加入到搅拌机内，均匀搅拌60～80s，同时减水剂和引气剂加入拌合水混合均匀，在将混合液10s内缓缓加入到混合料中，充分混合搅拌90～120s，得到高强高抗裂水工抗冲磨混凝土；本发明具有强度高、优异的抗冲磨性能、良好的抗裂性能等优点，大大降低了企业的施工成本与后期的运行维护费用。
