What is BS EN 934-4 - Admixtures for grouting prestressing tendons about?
Admixtures influence properties of cementitious mixtures in terms of fluidity, expansion, and volume change.
BS EN 934-4 is a European Standard that discusses admixtures for concrete, mortar, and grout.
BS EN 934-4 is the fourth part of the multi-series, and defines and specifies requirements and conformity criteria for admixtures for the use in grouts for prestressing tendons according to EN 447. BS EN 934-4 covers admixtures for use in site mixed grout only.
Note: Provisions for the use of grout admixtures are not part of BS EN 934-4 but are covered by EN 447.
