Abstract

The invention belongs to the technical field of concrete, and particularly provides a previous concrete. The previous concrete comprises cement, aggregate, macroporous resin and adhesive, wherein the macroporous resin is one of GMA-EGDMA (Glycidyl Methacrylate / Ethyleneglycol Dimetacrylate) macroporous resin, GMA-MBAA ((Glycidyl Methacrylate / Methylene-Bis(Acrylamide)) or macroporous resin or GMA-DVB (Glycidyl Methacrylate-Divinylbenzene) macroporous resin; and the adhesive is one of polyvinyl acetate, polyving akohol or butadiene styrene rubber. The previous concrete is high in compressive strength and permeation coefficient, can meet various construction demands on permeability of concrete, and is beneficial for maintaining ecological balance and realizing sustainable development.

Description

technical field [0001] The invention belongs to the technical field of concrete, in particular to permeable concrete. Background technique [0002] With the development of concrete technology, maintaining ecological balance and realizing sustainable development are also the pursuit goals in the field of building materials. Permeable concrete is an ecological and environmentally friendly concrete. It not only has a certain strength, but also has a certain degree of water permeability and air permeability. With the use of permeable concrete, water can quickly penetrate into the ground, and the road will not accumulate water and reflect light in rainy days, thus well mitigating the impact of impermeable pavement on the environment. [0003] Permeable concrete generally consists of cement, coarse aggregate, water and admixtures. In recent years, due to the application advantages of pervious concrete, a lot of research has been done on it. For example, CN101190833A discloses a...
