Benefits of technology

This patented technology allows create porous materials with improved physical characteristics such as increased compression resistance compared to traditional methods like cement production without them. Additionally, it enhances the durability of these materials due to added chemicals used during manufacturing processes.

Problems solved by technology

Technologies described include developing highly effective permeables (permeable), durably brushless surfaces called permafrost, create hydrophilic environments around buildings, provide protection against corrosion damage caused by acidification, maintain stable atmospherics during winter conditions without causing significant changes in indoor environment quality. Additionally, improving the design of permeabilities and freeze resistances of these products allows them to efficiently collect runoff and release stored energy while minimizing impact on human health. Overall, this technology helps preserve natural grass areas and promote sustainable development in cities.

Abstract

The invention provides a pervious concrete, and a preparation method and application thereof, and relates to the field of civil engineering concrete. The pervious concrete is prepared from, by weight, 60 to 100 parts of cement, 150 to 250 parts of stone, 5 to 15 parts of a reinforcing agent, 1 to 10 parts of a water reducing agent, 5 to 10 parts of vinyl acetate resin, 2 to 8 parts of polymethyl acrylate and 40 to 60 parts of water. The bamboo pulp fibers and the bagasse fibers are added into the components, so that the mechanical property of the pervious concrete is improved; vinyl acetate resin and polymethyl acrylate are added, so that the mechanical property of the concrete can be improved on the basis of ensuring the water permeability of the concrete, the water-permeable concrete is not easy to crack after being formed, and the service life of the water-permeable concrete is prolonged; and by controlling the polymerization degree of the polymethyl acrylate, the phenomenon that the pervious concrete is prone to bleeding or segregation in the stirring and mixing process is reduced.
