Chloride Permeability and Abrasion Resistance of Self-Compacting Concrete Incorporating Iron slag

Gurpreet Singh SIdhu

Abstract


The dumping of industrialized by-products is a primary burden because of ironclad environmental rules. Adoption of industrial by-products as an alternative fine aggregate in the concrete is the only quick fix. This study shows the exchange of iron slag with fine aggregate (sand) in self-compacting concrete (SCC).  Percentages of iron slag 0, 15, 30 and 45 were incorporated. Rice husk ash (15%) was used to prepare control mix in addition with cement. Experimental tests were conducted to check the fresh properties, strength and durability properties of SCC with iron slag. Tests were conducted for slump flow, V-funnel, U-box, L-box, compressive strength, rapid chloride permeability and abrasion resistance. The test finding (up to 90 days) of compressive strength and chloride ion permeability indicate that iron slag can be suitable used in making SCC. SCC mixes containing up to 45% iron slag gave lower permeability values than control SCC mix. The results of compressive strength of SCC are significantly better than control SCC.

Keywords: Compressive strength, Chloride permeability, Abrasion, Iron Slag.
