The Omani Artificial Pozzolans (Sarooj)

Cement, Concrete, and Aggregates, 2001
Abstract Sarooj is a local Omani term for artificial pozzolana produced by calcining clays. Calcined clay mixed with lime and water has been used as a cementing material for a long time. It has been used widely in hydraulic structures due to its good hydraulic properties and in military defensive installations due to its durability. This

Pozzolanicity of Calcined Clay

2015
Out 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 ...
