ADMIXTURES. How the ADMIXTURES affects the workability of the concrete (Lab Report Sample)


The task describe how the ADMIXTURES affects the workability of the concrete


1: AIR ENTRAINING CONCRETE ADMIXTURES They supply greater resistance to deicing chemicals, improve workability, lower water demands for a particular slump, reduce the amount of fine aggregate needs in the mixture. They also create a slight loss in the concrete strength.2: WATER REDUCING CONCRETE ADMIXTURE This reduces the water demands of the mix, maintaining workability, increase bond strength, reduce honeycombing, reduce cracking, increase bond strength of concrete to steel and reduce drying shrinkage.3: SET RETARDING CONCRETE ADMIXTURE. These agents are primarily used for delaying the setting time of concrete.
