Admixtures are used at very low addition levels on concrete. Nearly 90% of all admixture used is at a dose of less than 0.1% of active chemical on concrete weight. Even at this level of addition, their beneficial effect on concrete properties is significant. providing a more cost-effective mix with improved placing characteristics and better durability.
In spite of the benefits, the fact that admixtures are derivatives of the chemical industry means that they are regarded with suspicion by many ecological regulators. Our process cycle methodology is to identify the environmental impact of admixture's substances that may contribute more than 1% to the environmental impact. as well as showing the poten¬tial environmental benefits of admixture use. This information can than be used to show areas where future admixture development could be targeted to further improve the environmental profile and sustainability when used in the life cycle of concrete.
