Effect of Changing Fly Ash Content, Temperature, and Calcium Chloride Levels on Strength Development of Mortars and Time of Setting of Pastes

Abstract

This purpose of this project is to quantitatively develop the effect of temperature, fly ash content, and calcium chloride content on time of setting and strength development of pastes and mortars. These findings make it possible to explore the probable effects of increasing the fly ash content of concrete used for revetment mats. The reduction in strength resulting from increasing amount of fly ash proportional to the amount of portland cement could be compensated for by use of 2 percent CaCl2, but this accelerating admixture could not completely compensate for a loss of early strength development that would result from a temperature decrease of 30 deg F expected from summer to winter.
