The heavy hitters, including superplasticizers for extreme flow or strength. The Future: Smart and Sustainable Concrete
Combinations of water-reducing and setting-time controls. Science and technology of concrete admixtures
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: Concrete is the second most consumed resource on
Speeds up hardening for rapid repairs or winter pours. The history of admixtures is as old as the Roman Empire
) so that sunlight breaks down pollutants on the building's surface.
Slows down the "set," essential for long hauls in hot weather.
The history of admixtures is as old as the Roman Empire . Long before modern chemistry, Roman builders experimented with organic "potions" to make their concrete more workable and durable. They added , blood , and eggs to their mixes. These proteins acted as primitive air-entraining agents, helping the concrete withstand freeze-thaw cycles and making it easier for laborers to pour into the massive forms of the Pantheon.
