Abstract

Self-compacting concrete (SCC) is a concrete having special features, and is the most revolutionary development in concrete construction for several decades; since every country now faces a problem of skilled labour in construction industry. SCC provides rapid rate of concrete placement and hence faster construction times; it is more durable and also develops high early age strength. The exploitation of natural aggregates is harming environment and thereby necessitating sustainable construction industry. Several alternates to natural aggregates are being investigated to overcome this challenge, and few of them include manufactured aggregates, quarry waste, crushed sandstone aggregates, materials recycled from construction and demolition waste, copper slag, crushed sand from different mineralogical sources, marble and granite waste aggregates, aggregates etc. Research studies demonstrate that these waste or by-products may be used as partial replacement of river sand in concrete. Fly ash - a coal industry waste possessing Pozzolanic properties is highly recommended as cement replacement material for green initiatives. This paper illustrates the laboratory investigation results on SCC incorporating, European Federation of National Associations Representing for Concrete (EFNARC) guidelines, by complete replacement of fine aggregates with Processed Slag Sand (PSS) and partial replacement of cement with Class C fly ash. The results in terms of flow, strength and durability; for this novel SCC when compared with control concrete was found to be highly satisfactory and thereby encourage today’s Engineers to adopt SCC technology with this novel mix combination for sustainable development.
