Factors Affecting the Permeability of Porous Concrete
Pervious concrete is a type of porous, lightweight concrete made by mixing coarse aggregate, cement, and water. It contains no fine aggregate; instead, the surfaces of the coarse aggregate are coated with a thin layer of cement paste that binds the particles together, forming a honeycomb-like structure with uniformly distributed pores. As a result, pervious concrete exhibits air permeability, water permeability, and low weight.

Advantages of Gypsum-Based Self-Leveling Mortar
Gypsum-based self-leveling mortar is a dry, self-leveling powder mortar specially formulated in the factory by blending gypsum binder, specialized aggregates, and a variety of construction chemical additives to achieve uniform mixing. It is an ideal material for precise floor leveling in buildings and can serve as a leveling substrate for various floor finishing materials. The primary cementitious component of gypsum-based self-leveling mortar is gypsum, and it exhibits excellent self-leveling properties.
