Cement setting accelerator, first of all, at negative air temperatures (up to - 25 ° C).
The antifreeze additive NITSAL S45 is used for the preparation of concretes with a wide range of applications. Helps to improve the operational properties of the initial composition. The superplasticizer is indispensable for winter concreting, as it regulates the release of heat during hydration. When a small amount of superplasticizer is added, the long-term strength of concrete structures is ensured, porosity and permeability of the material are preserved. The setting time of Portland cement is significantly reduced. The NITKAL additive interacts best with low- and medium-aluminum cements at a stable temperature and medium humidity.NITCAL is designed for use at low temperatures - up to -25C ensures the viability of the solution. The specialists of the company "Protex-S" recommend using a superplasticizer to ensure the reliability and durability of concrete poured in the cold season.
