At present, various engineering applications require the use of
concrete, due to the strength requirements of the facilities being
built. Normal concrete can guarantee a certain level of strength
for buildings and facilities, but it is a challenge to effectively
conserve water since the water permeability and pervious area of
the ground are reduced. This reduction results in heat islands in
cities, and is adverse to the ecological environment. Therefore,
pervious concrete can be used as an alternate material. Pervious
