Abstract
The invention relates to a compound gelled material used in pervious concrete and a preparation method thereof. The compositions of the compound gelled material and the weight percentage thereof are that: 70- 90 percent of concrete, 5-15 percent of slag micro powder, 3-12 percent of fly ash, 1-3 percent of latex powder and 0.3-1.5 percent of water reducing agent. The pervious concrete used compound gelled material of the invention is powdered solid and has simple preparation technique and convenient transportation. Preparing the pervious concrete by the compound gelled material of the invention is the same with preparing common concrete, which does not need to change existing production equipment and production technique. The pervious concrete prepared by using the compound gelled material of the invention has good water permeability, air permeability and compression strength.
