Daraset® 300 is a liquid set accelerating admixture for concrete and mortar. It is highly recommended for use in the prefabricated sector when the ambient temperature is low.
Chloride-free, set accelerator based on nitrate Set accelerating admixture for concrete according to EN 934-2:T6
Mode of Action
Daraset 300 shortens the setting time of concrete, compensates for the set-slowing effects of cooler weather conditions and contributes to the development of higher early strengths. Daraset 300 can be used at temperatures above -15°C.
The constituent materials should be heated, and the temperature of the fresh concrete should be higher than +10°C. Only nonfrozen aggregates should be used. The substrate, rebar and molds should also not be frozen. The concrete must be protected against frost.
Formats: 24 litre, 220 litre or 1,000 litre.
