Feb 02, 2018 Concrete shrinks occur where there is not adequate water. The shrinks cause internal stresses that may culminate to cracks. The shrinkage additives work to ensure that this does not happen. Inhibits Corrosion. These additives are used where there is a presence of chloride salts. These chloride ions may corrode with steel reinforcements resulting to rusts. The areas that need this additive
