Permeable concrete curing agent
(Permeable floor curing agent)
I,Overview
A polymer material that can significantly increase the strength of permeable concrete, the appearance is gray powder, which can be used for permeable concrete base and surface course, suitable for concrete batching plant use, after mixing, the operation time can reach 3 hours at 30°C air temperature.

III,Features
High strength, can control the coagulation speed, has good fluidity, can make the permeable concrete surface layer stone particles evenly arranged, increase the aesthetics of permeable concrete, improve the construction speed, reduce labor intensity.
IV,Usage and dosage
Strength | Material | Doping ratio (kg) | Hardener ratio | Remark |
C20 | Cement: Stone: Curing Agent: Water | 320:1600:8:90 | 0.4% |
Cement is P.O 425# For ordinary Portland cement, the amount of water added is adjusted according to the season |
C25 | Cement: Stone: Curing Agent: Water | 350:1600:10:98 | 0.5% | |
C30 | Cement: Stone: Curing Agent: Water | 380:1600:12:110 | 0.6% |
V,Precautions
The permeable concrete mixed by the commercial mixing station needs to be transported by dump truck, and must be sealed and moisturized during transportation, and it is recommended to pave with a small excavator after unloading to the site, and then manually leveled and compacted, pay attention to maintaining the moisture of the permeable concrete during the construction process, and use a sprayer to spray and replenish water if there is water loss.
VI,Storage
Store in a ventilated and dry warehouse, the bottom of the pile is strictly protected from flooding, and the aggregate yard should be covered with rain.
VII ,Packaging and shelf life:20 kg/bag, plastic weaving; Dry and cool sealed room storage, shelf life 12 months.
