Preliminary Investigations on Strength Properties of Concrete Using Addition of Alccofine

This study presents preliminary investigations on the strength properties of concrete using addition of Alccofine. Concrete mixtures were prepared with varying percentages of Alccofine ranging from 0% to 20% and tested for compression strength and splitting tensile strength after 7, 14 & 28 days of curing. During the first week of curing (7 days), the concrete gains initial strength. Extending the curing period to 14 days allows for further hydration and strength development in the concrete. The 28-days of curing period is a critical milestone in concrete curing, as it represents the standard duration for assessing the concrete's compressive strength characteristics. The optimum percentage of Alccofine was arrived at15%. Exceeding the optimum percentage of Alccofine (20%) can lead to an adverse effect on strength due to potential issues like excessive pozzolanic reactions or changes in the concrete's microstructure. This information will help in determining the optimal proportion of Alccofine for achieving the desired strength and performance characteristics in the concrete mixtures.
