Embodiment Construction
[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0036] refer to figure 1 , the embodiment of the present invention proposes a preparation method of green self-compacting concrete, comprising:
[0037] S1: According to the accumulation mode of solid particles and the compressible accumulation model, determine the compaction index of the green self-compacting concrete, and calculate the packing density of the cementitious material system, the aggregate system, and the mixture system according to the compaction index;
[0038] S2: According to the packing density of the cementitious material system, the preselected cementitious material combination is obtained; the optimal sand rate is obtained according to the packing density of the aggregate system; Combining and the preferred sand rate, determine the volume ratio of the pre-selected cementitious material system an...
