masterease174; admixture for reducing viscosity of concrete

Concrete admixture - Kao Corporation

The present invention is directed to a copolymer for use in a concrete admixture which improves the workability of hydraulic compositions such as cement paste, mortar, concrete and the like. Namely, the admixture effectively reduces the viscosity of the hydraulic compositions under shear without causing setting retardation of the compositions.

PPTX Title Slide - PCA

Water-Reducing Admixtures. Adapted from Neville 1995. A water-reducing admixture is an admixture that increases workability without increasing the water content of concrete, or that permits a decrease in water content without decreasing the slump. Advantage may be taken for both purposes of a water-reducing admixture when designing concrete.

PDF Chapter IV Concrete Making Materials

Water-reducing admixture They are used to reduce the water content of a concrete mixture while maintaining a given constant workability. The resultant effect of reduced water content is increased strength and durability of concrete. Water reducers may also be employed to "plasticize"the concrete, i.e., to make concrete flowable.

Self Consolidating High Performance Concrete :: SCC

The high flowability of SCC is generally attained by using high-range water-reducing (HRWR) admixtures and not by adding extra mixing water. The stability or resistance to segregation of the plastic concrete mixture is attained by increasing the total quantity of fines in the concrete and/or by using admixtures that modify the viscosity of the
