Ammonium Nitrate and fertilizers. Ammonium Nitrate is generally used as a fertilizer. It is actually sold in the form of pellets that are coated with clay. The reason why it is very popular in agriculture is because of the high nitrogen amount in this compound.
Calcium nitrate is used in set accelerating concrete admixtures. This use with concrete and mortar is based on two effects. The calcium ion accelerates formation of calcium hydroxide and thus precipitation and setting. This effect is used also in cold weather concreting agents as well as some combined plasticizers.The nitrate ion leads to formation of iron hydroxide, whose protective layer reduces corrosion of the concrete reinforcement.he calcium ion accelerates formation of calcium hydroxide and thus precipitation and setting.
