Concrete Setting Accelerator

Using a cost-effective concrete setting accelerator enables year-round work on site or on a project. See the advantages Yara's NitCal offers over alternatives.

NitCal can be used without any risk to the quality of your concrete because it allows cold weather concreting, even in very severe weather, and prevents surface cracking when it's hot.

How NitCal works

NitCal concrete setting accelerator is a mixture of purified nitrate salts. It was specially developed by Yara to offer a range of advantages compared with other concrete accelerators on the market because it:

  • Neutralizes the retardation of concrete setting due to use of plasticizers
  • Optimizes the consumption of water and cement, when used in conjunction with a superplasticizer
  • Uses hydration heat to prevent freezing and does not shift the freezing point of water
  • Reduces corrosion
  • Works will all common cement types (CEM I, CEM II, CEM III) as well as calcium aluminate cement

NitCal is a cost-effective solution in a wide range of concrete pouring situations.

What's the recommended dosage for Yara NitCal as a concrete setting accelerator?

Your NitCal dosage will depend heavily on:

  • How much cement is used – it is recommended that preliminary tests are carried out on your site to get the right balance for anti-freeze features
  • Purposes it is being used for – dosage varies based on usage as a setting accelerator, corrosion inhibitor, or for anti-freezing or a compensate plasticizer retardation effect

Factors such as the type of cement used and the dosing method also need to be taken into consideration.

Please be aware that the "antifreeze" feature requires prior testing.

Chemical Applications

Concrete Corrosion Inhibitor

Concrete Corrosion Inhibitor

Choose a concrete setting accelerator that reduces the corrosion of reinforcements and increases durability and lifespan. This means overall life-cycle costs are lower as damage to reinforced concrete fittings through corrosion is reduced.
