Admixtures — Science And Technology Of Concrete

Combinations of water-reducing and setting-time controls.

Achieving compressive strengths over 100 MPa—strong enough to build the world’s tallest skyscrapers, like the Burj Khalifa . The Modern Toolkit: 7 Essential Powers Science and technology of concrete admixtures

Flows into every corner under its own weight. Combinations of water-reducing and setting-time controls

Chemicals that combat the natural "tightening" of drying concrete to prevent cracks before they even start. Science and technology of concrete admixtures

Through the science of admixtures, what was once a gray paste has become a high-tech material capable of reaching the clouds, lasting centuries, and—hopefully—protecting the planet.
