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 adopting the method, the consumption of
cement is small, the construction is simple, and the method is favorable for being popularized.
