Pervious concrete and construction method thereof

Abstract

The invention discloses pervious concrete and a construction method thereof, which relate to the technical field of concrete construction. The pervious concrete is prepared from the following perviousconcrete raw materials in parts by weight: 200 to 300 parts of cement, 1250 to 1350 parts of coarse aggregate, 5 to 280 parts of mineral admixture and 60 to 90 parts of water. The pervious concrete raw material further comprises a surface reinforcing agent, and the surface reinforcing agent is prepared from the following reinforcing agent raw materials in parts by weight: 5-10 parts of polypropylene fiber and 10-15 parts of triethanolamine. The anti-pressure performance is good. The construction method of the pervious concrete comprises the following steps of reinforcing agent preparation, mixing, concrete preparation, pavement pouring and the like. The construction method of the pervious concrete has the advantage that the dispersity of the reinforcing agent is conveniently improved.

Description

technical field [0001] The invention relates to the technical field of concrete road materials, in particular to a permeable concrete and a construction method thereof. Background technique [0002] Concrete is widely used in road construction and other fields due to its excellent compressive properties. With the progress of the times, urbanization is progressing rapidly, and urban roads are prone to waterlogging disasters during heavy rains, which brings inconvenience to citizens' travel, and the permeable concrete pavement has excellent water permeability, which can reduce waterlogging disasters to a certain extent, so in Sponge city roads, school playgrounds and park walkways are increasingly using pervious concrete materials. [0003] The patent with authorized notification number CN102162214B discloses a construction method of permeable cement concrete, which is composed of cement, stones, sand, water, water reducing agent, gravel and polypropylene fiber. The patent us...

Problems solved by technology

[0004] However, this patent uses polypropylene fiber as a reinforcing agent. During the use of polypropylene fiber, the polarity difference between polypropylene fiber and other cement concrete materials such as cement is large, and polypropylene fiber is not easy to combine with other cement concrete materials. It is conducive to the uniform dispersion of polypropylene fibers in other cement concrete materials, which is not conducive to giving full play to the reinforcing effect of polypropylene fibers, reduces the reinforcement efficiency of polypropylene fibers, and is not conducive to further improving the compressive performance of permeable concrete
