High-Range Water Reducers are used to reduce water demand at 12 - 30%. Giving the best workability, having superior slump retention and aiding in the production of High Performance Concrete (HPC) and Self Consolidating Concrete (SCC).

Importance of Water-Cement Ratio in Concrete

This is the biggest problem while designing a concrete mix with low w/c ratio. For overcoming this problem; we can use admixtures like Water reducing admixtures (WRA), superplasticizers (High Range Water reducer) etc. These admixtures are added to the concrete to achieve certain workability at low w/c ratio and make high strength and dense ...

Effect of Usage of Admixture in Concrete

Chemical admixtures are added to concrete in very small amounts mainly for air entrainment, reduction of water or cement content, plasticizing of fresh concrete mixtures or to control the setting time of concrete. These admixtures can be broadly catagorised as superplasticizers, accelerators, retarders, water reducers and air entraining admixtures.

The Benefits of Water Reducers in Concrete

2018/03/26 · The water reducer doesn’t evaporate; it helps increase the slump or flow without adding water. It also allows you to maintain the desired strength that you need in the concrete. This admixture will reduce the amount of water used

Water-Reducing and Set-Controlling Admixtures

Water-reducing and set-controlling admixtures offer precasters real advantages in improving their production capabilities. Water-reducing admixtures are used to produce concrete of higher strength, obtain specified strength with lower cement content, and increase the slump of a given mixture without an increase in water content.

How Mid-range Water Reducers Enhance Concrete Performance

water reducers contain a surf a c - tant, or “slickening agent,” that helps the concrete particles slide over and around each other more f re e l y. Co n t r actors say this slickness can be felt during concrete place-ment and finishing opera t i o n s , and that it often results in greater pro-ductivity and better surf a c e s .

Chemical Admixtures — What, why, & how? – Nevada Ready Mix

This increases strength or allows the cement content to be reduced while maintaining the same strength. Water-reducers are used to increase slump of concrete without adding water and are useful for pumping concrete and in hot weather to offset the increased water demand. Some water-reducers may aggravate the rate of slump loss with time.
