Abstract
The aim of this study was to develop Gum Acacia Karroo (GAK) as set retarding-water reducing admixture in cement mortars. Retarding admixtures are used to counter effect the accelerated hydration of cement at elevated temperatures by slowing down the retarding process especially during the day when concreting work is done. However most retarding admixtures available in the market are expensive, thereby making them out of reach for small consumers of concrete in Africa are expensive and not readily available. GAK, which contains soluble sugars, was investigated as a set-retarding water reducing-admixture. Setting time was measured in cement pastes with different dosages of GAK and a commercial retarding agent (Tard CE). Compressive strength, bleeding and flow test were investigated on cement mortars with the control being cement mortar without admixture. GAK was found to increase final setting time by 6 h above control. Compressive strength increased when water cement ratio was reduced from 0.5 to 0.4. Thermogravimetric analysis revealed increased dosage of GAK reduced hydration rate.
