Investigations on Fresh properties of Self Compacting Concrete with various mineral admixtures
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 9
Abstract
Self compacting concrete (SCC) is having enormous advantages compared with the vibrated concrete. Production of SCC requires a large amount of powder content, thus demanding the high quantity of cement with one or more admixtures. Using large quantity of cement leads to production demand and environmental pollution due to high energy consumption. In view of this aspect, mineral admixtures are used to replace the cement in high volume. Industrial by products such as fly ash, Silica fume and granulated blast furnace slag are used as mineral admixtures in SCC. These mineral admixtures can improve particle packing and decrease the permeability of concrete. This study investigates the influence of various mineral admixtures on the fresh properties of SCC. Cement is replaced with GGBS and FA in the range of 20, 40 and 60% and SF in the range of 5, 10, and 15% for all mixtures. Fresh properties of the SCC with these mineral admixtures are tested for slump flow, T 500, V-funnel flow, and L-box tests. The results indicate that all the mixtures shows improved fresh properties without segregation even at higher replacement levels.
