Hi Scott. Thank you for your question.

Permeable concrete is a kind of porous lightweight concrete made of aggregate, cement and water. It does not contain fine aggregates. A thin layer of cement slurry is coated on the surface of coarse aggregates and bonds with each other to form a honeycomb structure with uniform distribution of holes. It takes advantages of air permeability, water permeability and light weight.

Unlike other products, permeable concrete needs coarse aggregate as skeleton. Then the coarse aggregate need to mix with cement, admixtures and water to prepare finished products. This is contrary to our previous idea that the finer aggregate is, the better finished products are. In addition, it is also very important to ensure the porosity and permeability by mix proportion and additives.

For the preparation of coarse aggregate, Liming Heavy Industry has a fairly mature process system. For example, the secondary crushing system consists of jaw crusher and impact crusher shows good process. Only jaw crusher and impact crusher two major products, Liming Heavy Industry produced C6X, PE, PEW, CI5X, PF, PFW and other six series of models, in order to meet the demand for production. In addition, Liming Heavy Industry technicians will also combine the production site, application direction, transportation and other factors to customize a set of solutions for customers.

On the basis of more than 30 years of innovation and development, Liming Heavy Industry has accumulated a lot of market experience and reliable technology. Besides the preparation of coarse aggregate, it also participate in green building materials, building crushing, mining crushing and industrial powder, etc. industries with jaw crusher, impact crusher, hydraulic cone crusher, sand making machine, European type grinding mill and other large and medium-scale crushing and grinding equipment. The high quality products and good reputation have spread to more than 130 countries around the world, which brings higher value to customers.
