ACCELERATING ADMIXTURE FOR CONCRETE AND MORTAR
Perma Concrete Set is a chloride based accelerating admixture for use in non reinforced concrete and mortars. When admixed with concrete and mortar along with water Perma Concrete Set accelerates the setting time of the concrete and mortar and helps in achieving high early strength. This product is of use in shot-creting and guniting and in concreting and rendering in cold climatic conditions. Paver industry can highly benefit from the use of this product as it helps in early de-moulding and early shifting of the paver blocks to site saving enormous amount of space utilized in conventional curing and its strength development.
DIRECTIONS FOR USE
In case of shot-creting / guniting, Perma Concrete Set is mixed in the guaging water in the required proportion before addition to the dry mix. Hence it can be successfully used in both dry and wet shot-creting processes and for pre-casting elements. Perma Concrete Set is dosed through a separate dosing tank fitted above the mixer. It can be dosed manually as well after addition of required water.
Required dosage of Perma Concrete Set has to be arrived at site by practical trials. The dosage is dependent on temperature conditions, type of cement, type of acceleration required. We however recommend dosages of 1 to 10 percent by weight of cement. Lower dosages are however used in pre-cast elements and higher dosages are used in shot-creting. For waterproofing the minimum dosage of the product shall be 250 gms/50kg bag of cement.
Perma Concrete Set is compatible with all types of Portland cements including sulphate resisting cement. For use with other cements and along with other admixtures please seek the advice of your nearest Perma technical officer or Distributor. Perma Concrete Set should not be premixed with other admixtures. If other compatible admixtures are to be used in concrete then dose them separately.
