| Summary: | This paper presents a comparison between split tensile strength of normal concrete by adding 12% ultrafine slag (Alccofine) and varying percentage of steel fibers. Different materials like fly ash, silica fume, GGBS, rice husk ash has played important part in the development of high performance concrete. During recent past use of mineral admixture has gained pace. There is huge savings in terms of energy and cost when industrial by products are used as partial replacement of cement which is otherwise highly energy intensive. In this paper one of the mineral admixture ultra fine slag (alccofine) is used as a partial replacement of cement. Due to its appropriate size and shape this mineral admixture can be used comfortably even under low water cement ratio. In this paper cement is partially replaced by a fixed amount of alccofine i.e. 12% by weight of cement which has been calculated from previous literatures. Concrete cylinders with 12% alccofine and Steel fibers of varying weight were casted and tested at different ages of curing. Flexural strength was also determined using
similar variations of steel fibers and alccofine. Efforts have been done to investigate the performance of concrete using ultra fine slag and steel fibers which can be termed as high strength and high performance concrete. |
