Technical Field
The invention belongs to the technical field of building material preparation, and particularly relates to a pervious concrete formula and a preparation method thereof.
Background
Pervious concrete, also known as porous, gap graded, open pore or filter concrete, refers to a concrete with a microstructure of interconnected pores, which is an engineering material with high water permeability, constructed by avoiding the use of fine aggregates during the preparation. Environmental problems such as flood, water pollution, bad weather and urban heat island phenomena occur frequently and are global. The presence of impermeable pavements in highways and urban roads, which cut off the exchange of damp heat between the soil and the air, is one of the main causes of these environmental problems. Meanwhile, traffic accidents are reported to cause the death of one million people worldwide each year, with losses of nearly five billion dollars. The water permeability of the traditional road surface is insufficient, the anti-skid capability of the road surface is directly weakened in rain and snow, and the main reason of traffic accidents is caused. Unlike impervious concrete pavements, Pervious Concrete Pavements (PCPs) provide better rain drainage and snow melting to prevent safety issues for drivers in inclement weather conditions, such as slip, glare, fog and flood. In addition, the porous structure of the permeable pavement can preliminarily purify rainwater and serve as a tunnel for heat and moisture exchange of the atmospheric pavement, so that a positive environmental effect is generated.
