✦ Synopsis

A study was conducted to determine the effects of using kiln dust (a pozzolonic waste by.product of cement manufacture) as a cost reducing additive in blended cements. Cement quality, properties of mortar and properties of fresh and hardened concrete were investigatged in the laboratory. Shrinkage, creep and durabillity were also examined. The test results show that replacing 5 percent of cement by weight with kiln dust produces a mix exhibiting slightly greater shrinkage and creep and greater setting time than plain concrete but does not adversely affect other properties of mortar or concrete.
