Admixture - an overview | ScienceDirect Topics

Admixtures are ingredients that are added to the concrete batch immediately before or during mixing. They confer certain beneficial effects to concrete, including frost resistance, sulfate resistance, controlled setting and hardening, improved workability, increased strength, etc. Special concretes are made with coloring pigments, polymer latexes, expansion producing admixtures, flocculating ...
