How Concrete is Made

Through a chemical reaction called hydration the paste hardens and gains strength to form the rock-like mass known as concrete Within this process lies the key to a remarkable trait of concrete: it's plastic and malleable when newly mixed strong and durable when hardened These qualities explain why one material concrete can build skyscrapers bridges sidewalks and superhighways houses

Ettringite Formation and the Performance of Concrete

react with calcium aluminate in the cement to form ettringite within the first few hours after mixing with water Most of the sulfate in the cement is normally consumed to form ettringite at early ages The formation of ettringite in the fresh plastic concrete is the mechanism that controls stiffening At this stage ettringite is uniformly and discretely dispersed throughout the cement paste
