Problems solved by technology

The main disadvantage of this patent is: the prepared special concrete only has good water permeability, which only solves the problem of no water accumulation on the road surface in rainy days, but increases the drainage volume of the urban drainage system, increases the sewage treatment cost of the urban area, and cannot store water. Cannot effectively resolve the contradiction between the rapid development of urbanization and environmental protection

Abstract

High water concrete for sidewalks and a preparation method thereof belong to the technical field of special concretes. The concrete is composed of a gelatinization material, porous aggregate, water, a water reducer, redispersable emulsion powder and a foaming agent. The method includes breaking and grading the porous aggregate, conducting pre-wetting treatment on the broken aggregate, adding the gelatinization material, the water reducer, the redispersable emulsion powder and the water into the aggregate, evenly mixing the mixture, then adding foam into the mixture, stirring evenly and pouring the mixture on the sidewalks on site to prepare the high water concrete for sidewalks. The invention is simple in device and convenient to construct on site. The concrete prepared in the method has the advantages of being low in cost, good in water storage performance, water permeability and air permeability, capable of reducing water discharge of an urban drainage system and the like and has the function of natural plants. Use of the concrete is one of the effective measures to alleviate the contradiction between quick development and environment protection in urbanization construction. The high water concrete can be widely used on the surface of sidewalks or roofs.

Description

technical field [0001] The invention belongs to the technical field of special concrete, in particular to special concrete for sidewalks and a preparation method thereof. Background technique [0002] With the rapid development of urbanization in our country, the problem that the urban surface of our country is covered by reinforced concrete houses and impermeable concrete pavement is increasing, and the damage to the environment is becoming more and more serious. How to properly handle the relationship between my country's urbanization and environmental damage is one of the most important issues that our government, cadres and the masses are extremely concerned about. In addition, because my country's urban construction does not separate the rainwater and sewage discharge systems, the rainwater and sewage are discharged together, resulting in a large increase in the amount of urban sewage during the rainy season, and a large increase in sewage treatment costs. Therefore, i...
