Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a permeable concrete performance testing device. Background Art

[0002] Permeable concrete, also known as porous concrete, sandless concrete or permeable floor, is a porous lightweight concrete made of aggregate, cement, reinforcing agent and water. It does not contain fine aggregate, but is composed of a thin layer of cement slurry covered on the surface of coarse aggregate, which bonds with each other to form a honeycomb structure with evenly distributed pores. This makes permeable concrete breathable, water-permeable and lightweight. The produced permeable concrete needs to be sampled and tested for permeability using a permeable concrete performance testing device.
