Andreas Tselebidis, who has developed concrete mixes for more than 15 supertowers, says his assignment to design the mix for the world's first extra-high-strength architectural concrete supertower ...

A recipe for concrete that can withstand road salt deterioration Recycled materials used to make a better concrete mix Date: May 19, 2017 Source: Drexel University Summary: Engineers have known ...

As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. Calcium-based substances are heated at high temperatures to form ...

Cement, a component of concrete, produces 8% of the world’s carbon footprint. Looking to lower that percentage, Purdue University engineers have discovered a way to make concrete more sustainable.

Elsewhere, engineers tinker with the recipe for concrete, trying out substitutes for some of the cement, which makes up about 15% of the mix and functions as the glue that holds it all together.

A civil engineer from Drexel University is working on a new recipe for concrete, using cast-off products from furnaces, that can hold its own against the forces of chemical erosion.

Farnam created a method for using fly ash, slag and silica fume — leftovers from coal furnaces and the smelting process — in a new concrete mix that is more durable because it doesn’t react with road ...
