Permeable Concrete as a Road Pavement for a Storm water: A Survey Report

The invention discloses permeable concrete and a pavement construction method. The permeable concrete comprises the following components: 1300 to 1810 parts of broken stones, 92 to 152 parts of water, 350 to 400 parts of cement, 20 to 85 parts of mineral powder, 20 to 85 parts of silicon ash and 0.4 to 8 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 35 MPa; the flexural strength is above 5 MPa; the coefficient of water permeability is more than or equal to 2 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 adopting the method, the consumption of cement is small, the construction is simple, and the method is favourable for being popularized.
