Self-Compacting Concrete (SCC) or Self Consolidating Concrete is the present-day concrete that is being adopted the world over. The production of SCC involves the selection of appropriate materials and good quality control which is essential for the durability of concrete. The mineral admixtures and filler materials provide additional reduction to the porosity of the concrete. The primary objective of the present research work is to carry out the experimental investigations on durability properties of SCC with 20 different mix proportions, containing various percentages of filler materials like Limestone Powder (LP) and Marble Powder (MP), along with the mineral admixtures like Fly ash (F) and Silica Fume (SF). Experimental investigation on the durability properties for all the 20 mixes of SCC was carried out by conducting the Rapid Chloride Penetration Test (RCPT), Saturated Water Absorption Test, Acid Resistance Test, Sulphate Resistance Test, Water Permeability Test and Salt Water Resistance Test. From the experimental study, it is observed that the SCC mix with equal proportions F (10%), SF (10%), LP (10%) and MP (10%), exhibit better performance than the control mix in terms of strength and durability characteristics and thus it is concluded that the addition of mineral admixtures and filler materials have a pivotal role in the development of strength and durability aspects of SCC.
