Permissible Range for Using CapcoSet Cl in Concrete:
The allowable range for using The CapcoSet Cl is from 1% to 4% of the cement content (1 to 4 kg per 100 kg of cement material weight including cement, silica fume, slag, fly ash, and other similar pozzolans). The temperature at the time of concrete casting and after that, the concrete mix design, the thickness, and the volume of the concrete section are the main indices to determine this admixture. Specifying the optimum amount of this admixture is accomplished by considering the aforementioned indices and the required test in the laboratory. Besides, with respect to the reduction in the 28- day compressive strength of the concrete, it is recommended to reduce the water-to-cement ratio by using the water-reducing admixture. It is necessary to consider the reduction of the 28- day compressive strength anyway.
How to Mix CapcoSet Cl with concrete:
To use the admixture, it is necessary to dilute the admixture with water twice the volume of the admixture It is also necessary to take the following notes into consideration:
- Mix the concrete for 2 to 5 minutes after adding the admixture and assure the uniform distribution of the admixture in the mortar or grout.
- Avoid the direct contact of the admixture with the dry cement and aggregates
- In the case of using ready-to-use concrete it is recommended to add this admixture to the truck mixer before transporting and discharging concrete in the final section. However, it is necessary to subtract the water used to dilute the admixture and the water as much as the admixture volume (Before adding to the concrete) from the mixing water of the concrete in batching plant.
