Set-Control Additives-CapcoSet AS

Accelerating Admixture (CapcoSet AS)

CapcoSet AS is an Accelerating Admixture to speed up the setting time of the grouts and mortars. This admixture is chloride-ion free and does not lead to corrosion of the bars and steel surfaces. This product is produced based on the general requirements of Table 1 and the performance requirements of the Iran National Standard No. 2930-5. Also, this admixture meets the requirements of the EN 934-5 standard.

The advantages of using the CapcoSet AS in concrete

• Accelerating the initial and final setting time of the cement paste
• Increasing the compressive strength of the concrete at early ages

The usage of the CapcoSet AS:

• The production and implementation of the mortars with fast setting time
• The implementation of the spray mortar
• Grouting

Range and Method of Using the CapcoSet AS in the concrete:

Permissible Range for Using the CapcoSet AS in the concrete:

The allowable range for using The CapcoSet AS is from 2% to 10% of the cement content (2 to 10 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.

How to Mix the CapcoSet AS with the 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
