Properties Of The Omani Sarooj

Abstract

The fundamental properties of the Omani sarooj have been studied. Sarooj samples were collected from different sites to assess their pozzolanic activity. A laboratory testing program covering chemical and physical properties (consistency, setting times and compressive strength) were carried out. The effect of burning at different temperatures and durations on strength development was studied. The properties of sarooj were found to be dependent on the type of the clay, chemical composition, temperature and duration of burning. The controlling factors were viewed simultaneously in analyzing the test results. The optimum temperature that achieved the maximum compressive strength was found to be between 700°C and 800°C. At the optimum temperature, longer duration of burning produced shorter setting times.
