Anotácia textu normy ASTM C1622/C1622M-24 :
This specification covers cold-weather admixture systems to be added to hydraulic-cement concrete when the temperature of the concrete immediately after placement will be low. This specification stipulates tests of the cold-weather admixture system with suitable materials specified or with materials proposed for specific work, and provides three levels of testing. The apparatus used shall be suitable for low temperature environment. The concrete, cementitious materials, aggregates, and air-entraining admixture shall be tested and shall conform to the values of chemical and performance requirements such as initial setting time, compressive strength, shrinkage, durability.
