Preparation and application of superfine powder concrete
The invention provides superfine powder concrete which is composed of water, cement, superfine powder fly ash, medium sand and a water reducing agent. The water reducing agent is an aromatic sulfamate polymer. The fly ash superfine powder is doped into the concrete, so that the working performance and the mechanical performance of the concrete can be improved, more importantly, the early strength and the later strength of the concrete can be improved, and the 20-day setting strength of the concrete exceeds the conventional later strength of common concrete; the service life of the structure is prolonged, the annual cost of engineering is reduced, energy and resources are saved, the environment is protected, and huge technical economic benefits and social benefits are achieved.
本申请提供一种超细粉混凝土，由水，水泥，超细粉粉煤灰，中砂及减水剂组成，所述减水剂为芳香族氨基磺酸盐聚合物。本申请通过混凝土中掺用粉煤灰超细粉不但能改善混凝土工作性能、力学性能，更重要的是还可以提高混凝土早期和后期强度，其20天凝固强度即已超过普通混凝土常规的后期强度；延长结构使用寿命，降低工程年度成本、节约能源、资源和保护环境，具有巨大的技术经济效益和社会效益。
