[The following was acquired several months ago, from research for the concrete forum. It is for information only.]<br>
Concrete additives are used to produce specialized properties that enhance the durability of concrete. They span a wide range of materials, including lignosulfate or hydroxylated carbonic acid water reducers, lignin-based set retarders, sulfonate-melamine or modified lignosulfonate-based super plasticizers, chloride and nonchloride accelerators, and calcium nitrate corrosion inhibitors. The additives, for instance, can reduce concrete shrinkage 50%-80%, strengthen durability 30%, and prevent erosion or washout when concrete is being used for foundations in water. <br>
