Abstract: IMost commonly used composite building material in construction industry is Concrete due to ease of construction and its properties like compressive strength and durability. The basic ingredient of Concrete having adhesive nature is Ordinary Portland Cement(OPC). OPC is being replaced with Fly Ash and Metakaolin as these mineral admixtures possess pozzolanic properties which credit for strength gain and cost reduction in concreting. In this investigation, OPC is replaced up to 40% with Fly Ash and Metakaolin for M35 grade of Fibre Reinforced Concrete(FRC). Natural sand is replaced completely with Manufactured sand (M-sand). Steel fibres @ 1% of binder are used. Mechanical properties like compressive strength and split tensile strength at 7 days and 28 days age are tested. Additionally durability tests like water absorption and sorptivity after 28days curing are conducted. The test results indicated that 30% replacement of OPC was optimum for strength criteria, workability of Concrete was decreased with increase in replacement of OPC with Fly Ash and Metakaolin together.
Keywords: Fly Ash, Manufactured Sand, Metakaolin, Ordinary Portland Cement (OPC), Steel Fibres, Sorptivity and Water Absorption.
