The project was named C 4 S, which stands for Calcium Carbonate Circulation System for Construction, and led by Professor Takafumi Noguchi, as project manager, with Professor Ippei Maruyama ...

To make concrete, limestone, or calcium carbonate, is mixed with clay and other materials and then calcined at high temperatures, so CO2 is released via the thermal decomposition of calcium carbonate.

"This is one of the first demonstrations of microbial dissolution of calcium carbonate at a higher pH," said Karrie Weber, professor of biological sciences and Earth and atmospheric sciences.

Hungarian researchers have discovered unique bacterial communities in thermal waters that may help unravel the development of ...

Common Sources of Calcium: 1 cup of milk or calcium added soy milk=300 mg 1 cup of calcium added juice=350 mg take calcium carbonate (Tums, Caltrate, Oscal, Viactiv, most generics) with food - they ...

A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate ...
