Calcium nitrate of technical quality, used in the recipe of concrete mixes with accelerated curing; resistance to cracking and obtaining high-quality surface of the monolith and concrete products, as well as an anode inhibitor of corrosion processes of reinforcing steel in concrete. Allows you to achieve the strength and quality required on construction sites, regardless of weather conditions and the season, as well as speed up the workflow and reduce costs. The material is non-toxic, environmentally friendly, explosion-proof, fire-safe, highly soluble in water, including cold
It should be noted that calcium nitrate is a complex additive for concrete, due to its unique properties:
1. Acts as an accelerator, increases the strength characteristics (“8 hours) in small doses (0.5 – 1.5% by weight of cement).
2.Compatible with any plasticizers (lignosulfonates, superplasticizers on naphthalene and melamine bases, polycarboxylates, etc.)
3. Increases setting time due to the use of plasticizers, while the rheology (fluidity) does not change.
4. At low doses (1–2%), the strength characteristics increase for a longer time.
5. Prevents corrosion of the arma-tours (2 – 4%) caused by the increased content of chlorides.
6.Is an antifrosty additive (up to –20 С) at a dosage of at least 1%.
7.Used in the production of building materials and dry building mixtures.
