Porous cement concrete's excellent skid resistance, sound transmission ability and water permeability make it a good choice of material for highway construction. However, there are many differences in the manufacturing technology used for porous concrete and ordinary concrete. The main differences are constituent materials, workability test, mix proportioning, and indoor molding craft. Based on an analysis of the structural pattern of porous concrete applied in highway pavement, target porosity is viewed as the most important structural index, ...
