Understanding Limestone in Cement
{Answer} Recently, ASTM C150 was harmonized to meet the AASHTO M85 to allow up to 5% limestone in the cement. The history of limestone in cement is a little checkered, and as a result, there is some controversy in this decision, along with some confusion and concern. Here in the U.S. it is long past when finely ground limestone …

Limestone | Characteristics, Formation, Texture, Uses, & Facts
Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long …

Cities of the future may be built with algae-grown limestone
Global cement production accounts for 7% of annual greenhouse gas emissions in large part through the burning of quarried limestone. Now, a CU Boulder-led research team has figured out a way to make cement production carbon neutral—and even carbon negative—by pulling carbon dioxide out of the air with the help of microalgae.
