Inematic rock powder for railway high-performance concrete and preparation method of igneous rock powder
The invention discloses igneous rock powder for railway high-performance concrete and a preparation method of the igneous rock powder, and relates to the technical field of application of concrete mineral admixtures, the igneous rock powder for railway high-performance concrete comprises the following raw materials by mass: 80-90% of igneous rock powder mother rock, 0-5% of a grinding aid, and 5-20% of a reinforcing component, and 0-5% of a pore adjusting component. By adopting a binding material compatibility technology, data support is provided for introducing the igneous rock powder as an admixture into the concrete, efficient utilization of the igneous rock powder produced from the tunnel slag is realized, the problem of shortage of traditional mineral admixtures is solved, and the purposes of reducing the construction cost and protecting the ecological environment are achieved.
本发明公开了一种铁路高性能混凝土用火成岩石粉及其制备方法，涉及混凝土矿物掺和料应用技术领域，按质量百分含量计，所述铁路高性能混凝土用火成岩石粉的原料配比包括：80％～90％的火成岩石粉母岩，0～5％的助磨剂，5％～20％的增强组分，0～5％的孔隙调节组分。本发明通过采用胶凝材料配伍技术，为火成岩石粉作为掺和料引入混凝土中提供数据支撑，实现隧道洞渣生产的火成岩石粉的高效利用，用以解决传统矿物掺和料紧缺的问题，达到降低施工成本，保护生态环境的目的。
