Problems solved by technology

[0006] The above existing technical solutions have the following defects: polypropylene fibers can improve the strength of pervious concrete, and water reducing agents can improve the fluidity of pervious concrete to a certain extent, but as conventional additives, water reducing agents can improve the fluidity of pervious concrete. It cannot meet the requirements of tank truck transportation, so a permeable concrete that can meet the requirements of tank truck transportation is needed

Abstract

The invention relates to water-permeable concrete, and belongs to the technical field of concrete. The water-permeable concrete comprises the following raw materials in parts by weight: 80-100 parts of water; 1300-1700 parts of crushed stone; 350-400 parts of cement; 14-16 parts of silica fume; 2-10 parts of a water reducing agent; and 12-30 parts of an enhancer. The water-permeable concrete has the effect that requirements of tanker transportation can be met.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a permeable concrete. Background technique [0002] Permeable concrete is also called porous concrete, sand-free concrete, and permeable floor. It uses cement slurry to fill the gaps between aggregate particles through specific graded aggregates, and binds the aggregates together to form concrete with interconnected pores. Permeable concrete uses these pores connected to the surface to drain the accumulated water on the road surface in rainy days to facilitate the passage of pedestrians and vehicles. In addition, rainwater can also flow back into the ground through the permeable concrete to supplement the groundwater, thereby slowing down the decline of the groundwater level. When the weather is hot, moisture evaporates out through the pores in the pervious concrete to cool down, thereby mitigating the urban heat island effect. [0003] Permeable concrete consists of a thin l...
