Studying the permeability and strength of concretes containing silica fume, zeolite and fly ash using “Cylindrical chamber” method and British standard

Concrete is a porous material. Water and other fluids can penetrate it and effect its durability. So permeability is one of the most effective parameters of concrete structures durability. Design and construction of concrete, which has a less permeability in addition of providing the desirable compr...
