This paper reports the effect of Magnesium chloride (2) on Ordinary Portland Cement (OPC) concrete. The OPC concrete was produced with MgCl2 dosage of 0.2, 0.5, 1.0, 1.5 and 2.0 g/lit and deionised water was used in concrete mix (M20&M50). In addition to this, control specimens were prepared with deionised water (without MgCl2) for comparison. The compressive and tensile strengths were evaluated for 28 and 90 days. The results show that, as the MgCl2 concentration increases, the compression and tensile strengths decrease. The X-ray diffraction analysis for concrete has been carried out at 1.5 g/lit concentration.Keywords

Concrete is a composite material composed of aggregate bonded together by cement which hardens over time. Aggregate plays a major role governing the quality durability and workability of concrete. Owing to the extensive usage of aggregates in concrete the natural resources yielding these minerals (granite) are on the verge of depletion. Peak demand for granite has already resulted in the extensive leasing and aggressive mining of the granite reserves which in turn pollutes the sand, air and water in the vicinity of the quarry site. To avoid these consequences and conserve the mineral resource for the future generations it is essential to explore and evaluate other minerals from which viable replacement for granite can be established. One such innovation is the usage of locally available flaggy limestone as an aggregate replacement. The main aim of this paper is to study the fresh properties of concrete with the replacement of flaggy limestone aggregate in a variable fiber induced matrix, and determine its compressive and tensile strength.
