Nordquick AF9

Product description Alkali-free liquid admixture for wet-mix shotcrete and mortars. The use of NORDQUICK AF9 allows for setting times suitable for the filling of support arches and ensures high mechanical strength both at early and later stages of curing.

Shotcrete produced with NORDQUICK AF9 exhibits excellent early and final mechanical properties. NORDQUICK AF9 is used at a dosage of 7–9% by weight of cement. The product must be added to the concrete prior to spraying, through a fitting equipped with appropriate nozzles to ensure uniform dispersion of the admixture onto the sprayed concrete.
