Inematic rock mineral material for railway concrete and preparation method of igneous rock mineral material
The invention belongs to the technical field of building materials, and particularly relates to an igneous rock mineral material for railway concrete and a preparation method of the igneous rock mineral material. The igneous rock mineral material for railway concrete is prepared by mixing a grinding aid component to grind igneous rock mineral mother rock to a certain fineness, and then mixing the igneous rock mineral mother rock with an anti-adsorption component, a pore adjusting component and a reinforcing component according to a certain proportion, the mass ratio of all the components is as follows: 73.5 to 89.95 parts of igneous rock mineral mother rock, 0.05 to 1.5 parts of the grinding aid component, 1.5 to 4.5 parts of the anti-adsorption component, 0.5 to 2.5 parts of the pore adjusting component and 8 to 18 parts of the reinforcing component. According to the igneous rock mineral material for the railway concrete and the preparation method of the igneous rock mineral material, the physical indexes of the obtained mineral admixture meet the index requirements of I-grade fly ash; when the concrete admixture is mixed into concrete according to a proper mixing amount, the working performance and long-term durability of a concrete mixture can be effectively improved, and the technical requirements of Railway Concrete (TB/T 3275-2018) are met.
本发明属于建筑材料技术领域，具体涉及一种铁路混凝土用火成岩质矿物材料及其制备方法。一种铁路混凝土用火成岩质矿物材料是通过掺入助磨组分将火成岩质矿物母岩粉磨至一定细度后，再与抗吸附组分、孔隙调节组分和增强组分按一定比例混合而成，各组分质量比为火成岩质矿物母岩(73.5～89.95份)：助磨组分(0.05～1.5份)：抗吸附组分(1.5～4.5份)：孔隙调节组分(0.5～2.5份)：增强组分(8～18份)。本发明提出的一种铁路混凝土用火成岩质矿物材料及其制备方法所得到的矿物掺合料物理指标达到I级粉煤灰的指标要求；按适量掺量掺入混凝土中，可有效改善混凝土拌合物工作性能和长期耐久性能，并满足《铁路混凝土》(TB/T 3275‑2018)的技术要求。
