Water Reducers for Concrete Overview

 

1, What is water reducer?

No.1     Chemical admixture used to reduce the water content of a concrete mixture.

No.2     Surface-active polymer dispersant, referred as plasticizers/superplasticizers.

2,why water reducer?

No.1   Reduce water demand for the same workability  Higher strength and durability.

No.2   Increase the workability while maintaining same water/cement ratio and strength.

No.3   Reduce cement quantity for a given w/c, strength and workability.

3, How does water reducer work?

Disperse cement grains through electrostatic repulsion and/or steric hindrance

  Comparison of SMF, SNF and PCE

 

SMF condensates are good to achieve a high initial slump. However, due to their poor slump retention characteristics, they are unsuitable for long haul applications, and more particularly for ready mixed concrete. On the other hand, these admixtures are excellent for precast concrete, where the concreting time is short. They are also suitable for cold climates.

SNF condensates possess all the necessary characteristics to make them suitable for hot weather concreting. Mainly, these possess good slump retention characteristics, enabling their use in ready mixed concrete where long hauls are common. Slump retention characteristics are also improved by blending SNF with lignosulphonates, which is not possible in the case of SMF. The cost of SNF is also low, making it the most used superplasticizer in India and around the world. However, incompatibility issues.

SNF Superplasticizer from Beijing  China CNBM

Polycarboxylates and acrylic copolymers are the most effective of all the chemicals. These can cause a reduction in water content up to 40%. Thus, they are highly preferred to make high and ultra high strength concrete, where the w/c may be as low as 0.20. Generally, these chemicals exhibit excellent slump retention characteristics and do not cause any delay in the gain of strength of the concrete. The downside of these admixtures is their high cost. However, PCEs can work at lower dosages than SNFs and lignosulphonates. Thus, the overall cost of concrete is not affected. Only in the case of special concretes such as self compacting concrete (SCC), the use of PCEs can substantially increase the concrete cost. It must be stated, though, that making good quality SCC without these latest generation superplasticizers is almost impossible.
