Cement replacing limestone with volcanic rock could slash

Jun 30, 2021 High heat in giant kilns. Concrete’s CO 2 problem starts with limestone, a rock made primarily of calcium carbonate. 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 ...

Jul 06, 2017 Cement is a material which is highly compatible to the earth’s eco-system and most adaptable to sustainable development. Cement is a fine powder which sets after a few hours when mixed with water, and then hardens into a solid, strong material. Cement is mainly used to bind fine sand and coarse aggregates together in concrete.

A Review on Pyroprocessing Techniques for Selected Wastes

A Review on Pyroprocessing Techniques for Selected Wastes

Aug 17, 2020 Grinding of clinker consumes power in the range of 2.5 kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing. This paper discusses the cement manufacturing and grinding processes.

Jun 09, 2021 “We can take this rock, grind it and then heat it to produce clinker using the same equipment and infrastructure currently used to make clinker from limestone,” said Vanorio. Hot water mixed with this low-carbon clinker not only transforms it into cement but also promotes the growth of long, intertwined chains of molecules that look like tangled fibers when viewed under a microscope.
