Abstract

This paper reports the effect of Magnesium chloride (MgCl₂) 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.
