Permeable concrete reinforcement features prevention of hardening and dust, wear resistance, and impermeability sealing.
1. Prevent hardening and dust
Permeable concrete will also be subject to wear and dust during use, especially due to its strong water permeability and large gaps, which are easily clogged by dust. Permeable concrete reinforcement can chemically react with hardened components and loose loose materials to form insoluble materials.
2. Wear resistance
It can eliminate loose materials in permeable concrete, and the pressure resistance and wear resistance can be improved by more than 40%. The permeable concrete floor system is a porous, lightweight, fine-aggregate-free concrete. The surface of the coarse aggregate is covered with a layer of cement and bonded to each other to form a honeycomb structure with evenly distributed holes. Therefore, it is water-permeable, breathable and quality-free. Features of lightness; permeable concrete as environmental load reduction type concrete.
3. Impermeable sealing
The insoluble matter under chemical reaction can fill the capillary pores that block the concrete, forming a non-porous and dense surface layer, and the impermeability can reach more than 30%.
The main functions of the permeable concrete reinforcing agent are: 1. Make the stones fully wrapped by the cement slurry, keep the slurry stationary, and improve the adhesion of permeable concrete. This lays a good foundation for improving the strength of permeable concrete in the future.
2. Enhance the workability and viscosity of concrete, increase the surface activity of cement, and transform the dispersion of cement base.
3. Maintain the stability of the aggregate surface wrapped by the concrete slurry and greatly improve the compressive strength and bonding strength of the cement hydration body.
4. Improve the freeze-thaw resistance, durability and weather resistance of concrete. A good permeable concrete reinforcing agent can play a big role in permeable concrete, such as no stones falling off, no cracks in the road surface, water permeability in the road surface, and no alkalinity phenomenon, etc.
