Retarders for Concrete Mechanism, Types and Effects on
Retarders for concrete are used to delay the initial setting time of the concrete upto an hour They are generally used in the hot weather condition to counter the rapid hardening due to high temperature, thus allowing the time for mixing, transporting and placing Retarders also acts as water reducers In this article we discuss []Other benefit of using WRA is that higher concrete density is achieved which makes the concrete less permeable and have a higher durability Retarding admixtures The use of this admixture is defined in ASTM C494 There are two kinds of retarders, defined as Type B (Retarding Admixtures) and Type D (Water Reducing and Retarding Admixtures)Use of Water Reducers, Retarders, and Superplasticizer
Slow Concrete Cure Liquid Retarder Additive by SureCrete
SureCrete’s slow concrete cure liquid retarder is a water retardation admixture safe nonhazardous, waterborne additive for cement products It was designed specifically to slow the set of SureTex, SureSpray, or SureStamp that are seasonally adjusted to winter mix designRetarding admixtures, which slow the setting rate of concrete, are used to counteract the accelerating effect of hot weather on concrete setting High temperatures often cause an increased rate of hardening which makes placing and finishing difficult Retarders keep concrete workable during placement and delay the initial set of concreteChemical Admixtures Portland Cement Association
