More Information
Summary:The invention discloses green high-strength concrete. Components include 20-30 parts of microspheres, 20-40 parts of circulating fluidized bed desulfurized ash, 10-20 parts of coal ash, 0.5-1 part ofexcitant, 0.5-1 part of water reducer, 20-30 parts of cement, 20-30 parts of mineral powder, 10-20 parts of coarse aggregate and 10-20 parts of fine aggregate. A production method of the green high-strength concrete comprises the following steps that 1, the circulating fluidized bed desulfurized ash and the excitant are ground together for 30 min to 50 min to obtain modified circulating fluidizedbed desulfurized ash; 2, the modified circulating fluidized bed desulfurized ash, the microspheres, the coal ash and the water reducer are subjected to non-grinding mixing; 3, then the cement, the mineral powder, the coarse aggregate, the fine aggregate and a substance prepared in the step 2 are mixed to obtain the high-strength concrete. The concrete is excellent in performance, high in compressive strength and low in pre
