Abstract

This paper presents the effect of Potassium chloride (KCL) on OPC concrete. The OPC concrete produced with KCLdosage of 0.5, 2, 4, 6, 8, 10, 12 and 14 g/lit added in deionised water and the same water is used in concrete mix (M20 and M50). In addition to this control specimens were prepared with deionised water (without KCL) for comparison. The compressive and tensile strengths were evaluated for 28 and 90 days. The results exhibit that, as KCLconcentration increases, there is increase in compression and tensile strengths. The X-ray diffraction analysis has been carried out at 10 g/lit concentration.
