Triple Blending, Self Compacting, Superplasticiser, VMA, FlowabilityAbstract
SCC is generally defined as the “concrete that does not need compaction”. It means SCC gets compacted without external efforts like vibration, floating, or poking. The mix therefore is required to have the ability of flowing, filling voids and being stable. The present experimental investigation deals with the strength properties of fibrous SCC with triple blending. Fly ash and condensed silica fume (CSF) are both employed as replacement to cement at various percentages to give triple blending. By doing this kind of triple blending, it is expected to derive the beneficial properties of both the mineral admixtures. Concrete mixtures of two grades M25 and M30 are designed and tried for the SCC. Steel fibres of different aspect ratios ranging from 15-25 are tried in the present investigation. SCC mixtures with various combinations were tested for workability, compressive strength, split tensile strength and flexural strength. Comparisons are made. Based on the experimental investigation carried out in the present project, important and practically useful conclusions are drawn.
