Cement: replacing limestone with volcanic rock could

2021-6-30  To make Portland cement – the pasty main ingredient in modern concrete – limestone is mined, crushed and baked at high heat with clay and small amounts of other materials in giant kilns. Generating this heat usually involves burning coal or other fossil fuels, accounting for more than a third of the carbon emissions associated with concrete.

Emissions from the Cement Industry - State of the

2012-5-9  Though “cement” and “concrete” are often used interchangeably, concrete is actually the final product made from cement. The primary component of cement is limestone. To produce cement, limestone and other clay-like materials are heated in a kiln at 1400°C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement.

Using CO2 to Create a Limestone Rock Substitute

2021-5-11  Among these is the need for large amounts of rock material for aggregate – which is environmentally costly to mine, transport, and implement. Blue Planet’s biomimetic carbon capture process creates a limestone rock substitute that can replace natural limestone rock mined from quarries (the principal ingredient in concrete).

2018-2-21  sent different effects on strength development of concrete. Limestone contributes to young age strength of concrete and slag increases long term strength of concrete. When slag and limestone are used together, due to the synergy effect, ade-quate strength at both young age and long term age can be achieved (Papadakis 2000; Bonavetti et al. 2003). Many experimental and theoretical studies have been done about cement-slag-limestone ternary blended concrete.
