Seven Must-Use Concrete Admixtures (Additives)

ApplicationsBenefitsAdvantagesSet retarding concrete admixtures are used to delay the chemical reaction that takes place when the concrete starts the setting process. These types of concrete admixtures are commonly used to reduce the effect of high temperatures that could produce a faster initial setting of concrete. Set retarding admixtures are used in concrete pavement construction, allowing more time for finishing concrete pavem在thebalancesmb上查看更多信息
