High Performance Concrete Admixtures

Mid-range water-reducing admixtures were developed to increase the slump beyond the range available with regular water reducers without the excessive retardation that had been known to occur. High-range water reducers, commonly called superplasticizers, were developed for high-strength and high performance concrete applications.

High strength concrete properties, admixture, and mix

The time taken to achieve a specific strength is an important economic and design parameter in high strength concrete construction. In fact, a high early strength may bring far more practical and economic benefits than a high strength at a later age, in terms of early removal of formwork, increased productivity of precast units, early transfer of pre-stress, and early application of service loads.
