Abstract

Self- Compacting concrete (SCC) is a special type of concrete that is able to flow and compact under its own weight and can occupy all the spaces in the form without any vibration effect, and at the same time cohesive enough to be handled without bleeding or segregation. The required compaction properties are achieved by adding super-plasticizers and mineral admixtures such as fly ash, rice husk ash, silica fume, etc. The utilization of these treated industrial by-products as cement replacement will not only help to achieve an economical SCC mix, but it is envisaged that it may improve the microstructure and consequently the durability of concrete. This provides solution to disposal problems and other environmental pollution issues created by these otherwise waste products. This paper presents the results of an experimental study aimed at producing SCC mixes of M25 grade by using the Modified Nan Su method, incorporating five mineral admixtures, viz., Fly Ash, Blast Furnace Slag (GGBS), Silica Fumes, Rice Husk Ash, and Shell Lime powder as supplementary cementing materials. Also, this paper gives the comparison of these SCC mixes in terms of their properties like compressive, split tensile, and flexural strengths. The fresh concrete properties are also included in the study.
