Abstract
The natural materials provide a way for an economic production of concrete in hot weather conditions without using high cost chemical retarders. Effects of a natural additive on the properties of concrete vary with the additive type and volume. In this study, the effect of two natural materials as additives on the properties of concrete was investigated. Nine concrete mixtures were produced in three series with control mixes having 300 kg cement content. These control mixes were modified to have 1%, 2%, and 4% pumice or diatomite in place of cement. As the diatomite or pumice ratio increases, the initial setting and setting duration of concrete increase. ...
