Plastit NCL

Plastit NCL is a chloride free accelerating admixture based on a combination of formate and nitrate salts. It is supplied as a straw coloured solution that instantly disperses in water. Plastit NCL accelerates the early stages of cement hydration, producing more rapid stiffening and allowing strength gain to commence at an earlier stage. This effect is particularly noticeable at low temperatures and is most significant in the first 24 hours after mixing. 
Dosages outside the typical range quoted above may be used if necessary and suitable to meet particular mix requirements, provided that adequate supervision is available. Compliance with requirements must be assessed through trial mixes. 
Plastit NCL complies with BS 5075 Part 1 and with ASTM C494 as type C.
