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.
