Teknodure F

Portland cement-based product giving high strength, good flow and non-shrink properties. The mix design contains a specially formulated blend of fine cement powders, a graded high purity sand and a synergistic blend of admixtures. When the grout powder mixed with water, the product produces a material that develops a very rapid gain in early compressive strength, giving 25 MPa in two hours.

Placed grout is non-shrink and gives structural support and good vibration resistance. Teknodure F is chloride free and can be safely used in contact with reinforcing steel. The specialized mix design enables placement at low water content leading to good freeze-thaw stability, low water absorption plus resistance to oil, sea water and mild alkali attack. Placement thickness may be in the nominal range of 10–100 mm. For thicker sections, 6 mm aggregate should be added at a rate of up to one by weight of aggregate to one part by weight of Teknodure F.
