Set-Control Additives-Capcoset NCL

Accelerating Admixture / Chloride Free (CapcoSet NCl)

CapcoSet NCl is an Accelerating Admixture / Chloride Free for concrete casting in cold weather. This admixture is chloride-free and can be used for reinforced concrete. Also, this admixture is allowed in the pre-stressed concrete structures. CapcoSet NCl accelerates the first and second setting time of the concrete by increasing the rate of the cement hydration process and adds to the 1-day compressive strength of the concrete. Moreover, this product reduces the required time to protect the concrete in cold weather.

This product is produced based on the general Iran National Standard No. 2930-1 and the performance requirements of Tables 6 and 7 of the Iran National Standard No. 2930-2. Also, this admixture meets the requirements of grade C of the ASTM C494 Standard and the requirements of Tables 6 and 7 of the EN 934-2 standard. The physical and chemical properties of CapcoSet NCL are according to the following table and produced in the allowable changing range of Iran National Standard No.2930-1.

The advantages of using CapcoSet NCl in concrete include:

Range and Method of Using CapcoSet NCl in Concrete:

Permissible Range for Using CapcoSet NCl in Concrete:

The allowable range for using The CapcoSet NCl 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. To increase the 28-day compressive strength, it is also recommended to use the water-reducing admixture to reduce the water-to-cement ratio.

How to Mix CapcoSet NCl 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.
