Analysis of Concrete Containing Different Admixtures as Partial Replacement of Cement
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 7
Abstract
Concrete is the most extensively used man-made construction material in the world. Its most important quality is its versatility and the ability to design the concrete of any required properties according to the environment. . Human development in today’s scenario is impossible without the excessive use of concrete. Cement is the most important component of concrete. Unfortunately production of cement emits a very large amount of greenhouse gases and possess a very potential threat to the atmosphere. Thus it is inevitable for the sustainable development of human life that the dependency on cement to obtain strength in concrete should be lowered. This is the main reason to obtain a suitable replacement of cement to obtain high strength concrete at a low cost incurred. Also the modern constructions require very high strength in concrete which is only possible by mixing a suitable quantity of admixtures in the concrete. Silica fume, Rice Husk Ash and Iron Slag are abundantly available industrial waste products in India. Due to the latest imposed rules and regulations their disposal has become costly. Thus it is necessary to find a suitable useful way to utilize these waste materials. These materials have high siliceous content and pozzolanic properties thus these can be used as a replacement of cement in concrete mix and may also be used as admixture to obtain high strength. Flexural and compressive strengths are the two most important criteria that determine the performance of concrete in any field usage. Thus it is pertinent to obtain the effect of these admixtures on the flexural and compressive strength of concrete. A comparative study can analyze the relative effect of these admixtures on the strength of concrete so that the most suitable admixture can be utilized according to any existing situation.
