Preparation method of green high-performance concrete
The invention discloses a preparation method of green high-performance concrete, and relates to the field of preparation methods of concretes. The green high-performance concrete comprises cement, an addition, aggregate, an admixture and water, wherein the cement is P.O42.5-grade cement, various indexes meet requirements, the addition comprises fly ash, carbide slag and kaolin, the aggregate comprises building crushed materials, sand and broken stone, the admixture comprises a water reducing agent, an accelerator and an air entraining agent, and the water is common tap water. According to the invention, the problem of treatment of most building waste can be fundamentally solved while the transportation amount and the use amount of natural aggregate are reduced, mining of mines is reduced, storage of building waste is reduced, the engineering structure is improved through the environment-friendly high-performance concrete, the service life of the structure is prolonged, the engineering structure adopts high-performance concrete so as to save resources and reduce the engineering cost, and the cost of raw materials can be effectively reduced so as to reduce the cost of concrete and facilitate environmental protection and sustainable development.
本发明公开了一种绿色高性能混凝土的制备方法，涉及混凝土的制备方法领域，本发明包括水泥、掺合料、集料、外加剂和水，水泥为P·O42.5级水泥，各项指标符合要求，掺合料包括粉煤灰、电石渣、高岭土，集料包括建筑碎料、砂、碎石，外加剂包括减水剂、速凝剂、引气剂，水为普通自来水，本发明可以从根本上解决大部分建筑废料的处理问题，同时减少运输量和天然集料的使用量，减少了矿山的开采，减少了建筑垃圾的存放，同时绿色高性能混凝土改善了工程结构，结构使用寿命增长，工程结构采用高性能混凝土可以节约资源、降低工程造价，可以有效的降低原材料的成本，从而降低混凝土的成本，利于环境保护和可持续发展。
