Impact-resistant and wear-resistant concrete for civil engineering and preparation method thereof
The invention discloses impact-resistant and wear-resistant concrete for civil engineering and a preparation method thereof, and the impact-resistant and wear-resistant concrete comprises the following components in parts by mass: 30-40 parts of cement, 40-80 parts of aggregate, 0.1-2 parts of an additive, 0.1-2 parts of carbon fibers, 0.1-0.5 part of organic fibers, 10-15 parts of ceramic particles, 0.5-3 parts of a nano material, 5-10 parts of a recycled material and 10-25 parts of water, wherein the aggregate comprises fine aggregate and coarse aggregate, the fine aggregate adopts tungsten steel slag with the particle size of 0.1-5 mm, and the coarse aggregate adopts basalt particles with the particle size of 5-20 mm; classC fly ash cement is adopted as the cement; the additives comprise a water reducing agent, a reinforcing agent, a retarder and an anti-freezing agent. The concrete adopting the formula provided by the invention has better durability and anti-freezing and anti-cracking properties, is more uniform when being stressed, and delays the generation of cracks.
本发明公开了一种土木工程用抗冲耐磨混凝土及其制备方法，按照质量份数计，包含以下组分：水泥30份‑40份、骨料40份‑80份、添加剂0.1份‑2份、碳纤维0.1份‑2份、有机纤维0.1份‑0.5份、陶瓷颗粒10份‑15份、纳米材料0.5份‑3份、再生材料5份‑10份、水10‑25份；其中，所述骨料包括细骨料和粗骨料，所述细骨料采用了粒径为0.1‑5mm的钨钢渣，所述粗骨料采用了粒径为5‑20mm的玄武岩颗粒；所述水泥采用了ClassC粉煤灰水泥；所述添加剂包括减水剂、增强剂、缓凝剂及防冻剂。采用本发明配方的混凝土，其具有较好的耐久性和抗冻抗裂性，其在受力时更加均匀，延缓裂纹的产生。
