Comparative Analysis of Compressive Strength of Concrete by Replacing of Cement by Fly Ash with Conventional Concrete

Today, the development of infrastructure, industry and housing is necessary. Without concrete, the built environment would fail to accommodate our modern and demanding lifestyles. Given our reliance on concrete, it will inevitably play a major role to pursue sustainable development in any country. At its most basic, concrete is a mixture of aggregates, cement, sand and water. With appropriate mix design, concrete can be tailored for any construction requirement. Understanding the role of aggregates in concrete is fundamental to the production of good concrete as aggregates have their greatest influence on the performance of fresh concrete. Study all of constitutes in concrete mixtures, including aggregates, in order to obtain a comprehensive understanding of the behaviour of the final product. As a result of such considerations, it is clear that the role of aggregates is crucial to ensure satisfactory performance of mixtures since they govern the volumetric stability of concrete. In addition, aggregates have an important effect on concrete strength by providing rigidity to the material which governs resistance to applied loads and undesired deformations. The aim of the study is to assess the effect of use of fly ash in concrete as compare to cement concrete elements in marine condition of. - To compare the compressive strength of concrete by replacing 100% percentage of cement by fly ash with conventional concrete at constant molarity , as well as to study, the effect of varying curing time period under normal condition.
