Additives and admixtures for concrete are chemical substances added to concrete to improve its physical and chemical properties. These components represent a wide array of products with varying chemical properties. The main difference between admixtures and additives is the stages at which the substances are added to concrete or cement.

The addition of slag has been shown to reduce greenhouse gas emissions from concrete manufacture by more than 95%. Researchers have now discovered that the concrete delivers. "In our tests, we've replaced up to 40% of the cement normally used in concrete," says Senior Researcher Per Anders Eidem at SINTEF Helgeland, located …
