Machine-made sand reactive powder concrete using solid waste stone powder and preparation method of machine-made sand reactive powder concrete

The invention relates to the field of high-performance building materials, in particular to machine-made sand reactive powder concrete using solid waste stone powder and a preparation method of the machine-made sand reactive powder concrete. The concrete is prepared from the following raw materials in parts by mass: 1145 to 1155 parts of a composite cementing material, 1245 to 1255 parts of fine aggregate, 38 to 42 parts of steel fiber, 0.8 to 1.2 parts of a de-foaming agent, 35 to 52 parts of a water reducing agent and 205 to 209 parts of water, the composite cementing material comprises cement, silica fume, microbeads and mineral powder, and the fine aggregate comprises 20-40-mesh quartz, 80-120-mesh quartz sand, machine-made sand and stone powder. According to the machine-made sand reactive powder concrete prepared from the solid waste stone powder in a large mixing amount, a large amount of solid waste stone powder can be consumed, solid waste resource utilization is achieved, the problem that a large amo
