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. The Chemical Revolution: Master of Flow
The heavy hitters, including superplasticizers for extreme flow or strength. The Future: Smart and Sustainable Concrete Science and technology of concrete admixtures
Chemicals that combat the natural "tightening" of drying concrete to prevent cracks before they even start. The history of admixtures is as old as the Roman Empire
