Construction Method Of Modified Porous Cement Concrete Base

Porous modified cement concrete base is a new pavement structure that can achieve theabove requirements, which can change the structure layer existing density board intoporous skeleton structure layer. It can change the structure formed by the continuousgradation connected compactness into a single particle diameter punctate, forming netframework. So it exhibits excellent bending and anti fatigue performance. The colloidmodifys the chemical property of the existing ordinary portland cement to achieve antifreeze thawing and contact with water does not plasticizing and not reduce strength.Experiments show that, the anti fatigue ability of existing ordinary concrete cannot catch upwith the modified cement concrete.
