More Information
Summary:The invention discloses permeable concrete and a pavement construction method. The permeable concrete comprises the following components: 1350 to 1800 parts of broken stones, 90 to 150 parts of water, 300 to 350 parts of cement, 10 to 70 parts of mineral powder, 10 to 70 parts of silicon ash and 0.3 to 7 parts of water reducing agent; if necessary, organic intensifying agent can be added. The construction method comprises the following steps: permeable concrete is mixed, poured and cured, an expansion joint is cut, and the filling and the other processes are performed. Concrete pavement prepared by the method has higher strength and water permeability, and the compression strength can reach or exceed 30 MPa; the flexural strength is above 4 MPa; the coefficient of water permeability is more than or equal to 1 mm/s; the requirements for the permeable concrete pavement can be fully satisfied. The permeable concrete is suitable for the construction of permeable concrete pavement, squares and parking lots; by ado
