LAKHTA KMD PRO concrete admixture — complex modifier for concretes and mortars

LAKHTA KMD PRO admixture is a one-component water-soluble complex of mineral and chemical modifiers for concretes and mortars on Portland cement, self-stressing and oil-well cements. According to laboratory tests, it raises the water impermeability grade of the control concrete by 7 steps, from W2 to W16, increases the compressive strength at 28 days by 40 % and provides frost resistance up to F800. The admixture is added as a dry powder together with the dry components or as a solution in the mixing water; it is not used with other complex admixtures of a similar type.
