STUDIES ON PORTLAND POZZOLANA CEMENTS CONTAINING ENDOD, A SOAP BERRY PLANT

Water extract from Ended retards both the initial and final setting times of portland pozzolana cement paste. For a given water/cement ratio (0.66) the slump of the concrete mix containing 0.00, 0.02,0.05,and 0.08% of Endod increases from 2 to 9 mm and 3 to 11% sand and cement mixture was retrieved from the mould of concrete cubes. The average unit weight of the concrete cubes prepared with 0.00, 0.02, 0.05, 0.08% of Ended were 2.13, 2.04, 1.92, and 1.78 (for 28 days old) kg/L respectively.
