Natural pozzolans for concrete
Economic Geology, 1951Many geologic formations in the United States yield pozzolans or materials which can be converted into pozzolans by grinding and calcination. When properly selected, processed, and used, pozzolans will reduce costs, improve quality of concrete, protect concrete against effects of reaction between aggregate and cement alkalies, and inhibit attack by ...

Greening of Mortars with Pozzolans
2008Growing interest in sustainable building has created a strong interest in fly ash and other coal combustion products (CCPs). Emergence of agencies like the U.S. Green Building Council (USGBC) and the Coal Combustion Products Partnership (C2P2) of the USEPA has accelerated this trend.

Pozzolanicity of Calcined Clay
2015Out of the three major clay mineral groups, viz, kaolin, smectite and palygorskite – attapulgite, the cement science primarily focuses on the first group to be used on calcination as a pozzolanic admixture. The general understanding is that the dehydroxylation of dehydrated kaolinite in the temperature range of 550 – 650 °C apparently yields an x-ray ...
