Embodiment 1~3
[0063] An ultra-high-performance concrete, raw materials: cement, silica ash, mineral powder, mechanism sand, gravel, steel fiber, water reducing agent, water, calcium sulfate-calcium sulfate composite expansion, bisexual ion polymer, 2 2, 2 -Methyl-2-propane, porous silicon micro powder, high water absorption resin, inorganic gel coagulant, light-yaki carbonate? According to the cooperation ratio in Table 1, there are three groups of implementation. It should be noted that the cement slurry solution of high water absorption resin in the embodiment is 30 times the water absorption multiples of the cement slurry, and the actual water glue ratio of the embodiments of each group is 0.17.
