What is Pervious Concrete? Pervious concrete is a structural concrete pavement with a large volume (15 to 35 percent) of interconnected voids. Similar to normal concrete, pervious concrete is made from a mixture of cement,

Concrete Spalling Currently, there are two mechanisms concerning the occurrence of spalling: 1- the pore pressure build up causes spalling in the cement matrix and 2- thermal and mechanical stresses. In 1997, Anderberg gave an account

Corrosion of Embedded Metals in Concrete Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel.
