Influence of Strong Acids (Hydrochloric and Sulphuric) In Water on Properties of Natural Admixture Cements
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 1
Abstract
ABSTRACT: Admixtures and the water have an important role on application of concrete. The study is aimed at investigating the effect of strong acids as mixing water on setting times, soundness and compressive strength of admixture cements. This paper therefore presents the result and findings of an experimental research on the influence of strong acids on setting and strength development of admixture cements. In the research PPC plus 10% silica fume was added by weight and cubes were casted with deionised water and deionised water containing strong acids of HCl and H2SO4. The results shows the HCl and H2SO4 in deionised water accelerate the intial and final setting times in all concentrations. Both HCl and H2SO4 in deionised water decrease the compressive strength from early age (3-days) to the maximum age (2years). In the present work analysis the hydration characteristics of the admixture cements using the techniques of X-ray diffraction analysis and useful conclusions are obtained regarding the influence of strong acids.
