Fly ash, a coal-burning power plant byproduct that contains an aluminosilicate and small amounts of lime, is also being tested as a possible pozzolanic material for cement. After the refinement of Portland cement, the next major innovation in concrete technology occurred during the late nineteenth century, when reinforced concrete was invented. Mixtures with entrained air in excess of 20% by volume are used to keep the strength low.

Mihri Ozkan Mihri Ozkan, a professor of electrical engineering in UCR’s Bourns College of Engineering is organizing the event after being selected as UCR’s first Faculty Climate Action Champion. After an initial inflammatory response, there was no sign of further adverse tissue reactions. It can take 48 to 72 hours in cold or very dry weather. It has been called limestone dust, washed sand, quarry waste, and stone dust just to name a few. Plastics get their name from a word that means flexible—and their uses are just as diverse.
