The concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scientists have demonstrated a way to ...

Researchers have developed a nondestructive and noninvasive optical technique that can determine the setting times for various types of cement paste, which is used to bind new and old concrete ...

Cement is one of the most-used materials in the world, and one of the highest emitters of global CO2 emissions. As demand for ...

One of the main benefits of pozzolanic materials (derived from the volcanic ash the Romans used in their cement mixes) is its potential to significantly lower CO ₂ emissions in cement production.

During the mid-twentieth century, once it was known that adding 1-2% of calcium chloride improved the strength and accelerated the hydration process, chlorine was regularly and intentionally added to ...

There are three primary objectives for cold weather concreting: 1) protect the newly placed concrete from early-age freezing, 2) protect concrete to ensure adequate strength development, and 3) ...

The DuraForce line offers a topical densifier and multiple integral products, such as a hardener, a waterproofer, and a vapor mitigation product that carries a lifetime warranty. DuraForce(i) is a ...

Researchers develop innovative hydrogel-cement composites inspired by biomineralization, enhancing strength and thermal efficiency for sustainable construction.
