Superplasticizing admixtures for concrete

Superplasticizing admixtures for concrete which comply with the general requirements of EN934-1:2008 and the additional requirements of EN934-2:2009+A1:2012, Table 3.

Admixtures are chemical materials added during the mixing process of concrete in a quantity not normally exceeding 5% by mass of the cement content of the concrete to modify the properties of the mix in the fresh and/or hardened state.

A high range water reducing/superplasticizing admixture is an admixture which, without affecting the consistency, permits a high reduction in the water content of a given concrete mix, or which, without affecting the water content increases the slump/flow considerably or produces both effects simultaneously.
