Laboratory study for optimal mixing scheme of pervious concrete containing additive of microsilica fume based on maximum compressive strength and permeability

One of the useful and efficient ideas in pavement and flooring is use of permeable concrete which is called pervious concrete. Pervious concrete that has many economic and especially environmental impacts can be used for reducing surface runoff during rainfall, delaying the entry of rainwater into t...

Pervious concrete that has many economic and especially environmental impacts can be used for reducing surface runoff during rainfall, delaying the entry of rainwater into the sewage system due to its absorption by the ground, improving the quality of groundwater due to lack of water flow from the ground and contact with possible contamination.
