Science And Technology Of Concrete Admixtures Apr 2026

The heavy hitters, including superplasticizers for extreme flow or strength. The Future: Smart and Sustainable Concrete

As we move into the 21st century, admixtures are no longer just about strength; they are about . Concrete is the second most consumed resource on Earth, and its production is a major source of CO2cap C cap O sub 2 Modern science is turning to: Science and technology of concrete admixtures

Speeds up hardening for rapid repairs or winter pours. ) so that sunlight breaks down pollutants on

) so that sunlight breaks down pollutants on the building's surface. They act like microscopic magnets, wrapping around cement

The solution came in 1981 with the invention of in Japan. These "comb-shaped" molecules revolutionized construction. They act like microscopic magnets, wrapping around cement particles and pushing them apart through electrostatic and steric repulsion. This allows concrete to be "fluidized" exceptionally well without adding extra water, leading to the creation of:
