Superplasticizer Is Useful For Reduce

The superplasticizer is very useful to reduce mixing water in fresh concrete, which results in the enhancement of watertightness and strength of hardened concrete. But it has a limit of not preventing steel bar embedded in concrete from corrosion under critical corrosive environments. Thus, this study aims at developing a nanohybrid agent ...

Superplasticisers - an overview ScienceDirect Topics

Peter A. Claisse, in Civil Engineering Materials, 2016 29.7 Ultra-high strength concrete 29.7.1 High-range water reducers. Powerful superplasticisers may be used to achieve w/c ratios below 0.3, and very high strengths. These mixes have very good durability, and permit fast construction of very tall buildings. However, the modulus of elasticity may not increase as much as the strength.
