Abstract

The invention discloses pervious concrete which is characterized in that the pervious concrete is prepared from the following components in parts by mass: 1500-1600 parts of coarse aggregate, 320-420parts of a cementing material, 105-114 parts of water and 4.5-5.9 parts of a water reducing agent. An anti-corrosion material in the formula has remarkable plasticizing effect, micro-aggregate effect,morphological effect and temperature peak reduction effect, and the mechanical property, abrasion resistance and denudation resistance of the pervious concrete can be improved through the excellent characteristics of the anti-corrosion material itself and the improvement of the continuous grading of the microstructure of the cementing material, so that the durability of the pervious concrete is improved, and the service lifetime of the pervious concrete is prolonged.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to permeable concrete. Background technique [0002] The country proposes and strongly calls for the construction of a "sponge city", that is, when it rains, the city should have a better ability to absorb, store, purify and infiltrate water, and infiltrate the water on the surface through itself and the grassroots, thereby reducing the surface water. runoff, maintain the groundwater level, purify water quality, and effectively reduce the load on urban drainage systems and rainwater accumulation in low-lying areas. As the key material of sponge city, permeable concrete also develops rapidly. Due to the poor mechanical properties of existing permeable concrete (compressive strength of actual permeable concrete in engineering construction is about 20MPa, flexural strength is about 2MPa), plus Due to the particularity of the structure of permeable concrete, ther...
