More Information
Summary:The invention belongs to the technical field of building materials, and particularly relates to shrinkage-compensating ultra-high performance concrete prepared from tailing sand and a preparation method. The invention provides shrinkage-compensating ultra-high performance concrete prepared from tailing sand and a preparation method thereof. The concrete is prepared from the following components inparts by weight: 400 to 1200 parts of tailing sand, 100 to 300 parts of tailing sand powder, 500 to 800 parts of cement, 100 to 200 parts of silica fume, 0 to 800 parts of fine aggregate, 120 to 200parts of steel fiber, 8 to 12 parts of additive and 160 to 190 parts of water. According to the invention, the chemical components and hardness characteristics of the tailing sand are combined, wherein the tailing sand powder is used as a powder material to form a new ultra-high performance concrete material composition system, so that the full utilization of waste resources is realized, the shrinkage of the ultra-high per
