Concrete additive

Additive D-5 is a complex multifunctional additive that significantly improves almost all the main properties of concrete and mortar. At the same time, the manufacturer is confident that the main property of additive D-5 is to impart maximum possible water resistance (W20 and more) and sulfate resistance (on ordinary Portland cement) to concrete. Concretes with additive D-5 can be used for a long time (at least 50 years) in water-saturated soils or directly in water without the use of any additional waterproofing, including in an aggressive environment, including sewage and sea water. Additive D-5 seals all microcracks and capillaries in concrete, so there is no capillary moisture suction in concrete with D-5. In addition to the above, additive D-5 almost 2 times accelerates the strength gain of concrete and increases the strength of concrete at the age of 28 days by 30-50% compared to concrete without additives. At the same time, it plasticizes the concrete mixture well and prevents its stratification. It has a unique property of "self-healing" through cracks, which ensures the impermeability of "cold" joints in concrete.
