Popis: Now a days, preparation of concrete with conventional materials becomes more costlier due to the growing demand of construction materials. It will lead construction industry, to determine the alternative materials for the conventional without compromising the quality and quantity of construction. After numerous investigations, it is accepted that the preparation of concrete with alternative or industrial waste materials will be possible. In modern days, variety of industrial waste materials like fly ash, silica fumes, paper pulp, GGBFS, brick and quarry dust, etc., are disposed directly to the environment will causes various health, environmental and economic issues. So, it is necessary to effective disposal or treatment method, in order to reduce the above-mentioned social problems. Fly ash (FA) and waste steel slag (SS) are attempted to utilize an effective replacement material for the ingredient concrete. In this study, waste material from steel making industry was used as a partial replacement for fine aggregate (FIA) by varying replacement percentages from 0% to 60% at an interval of 10% in M30 grade high volume fly ash concrete (HVFAC) with different proportions of fly ash (40%, 50% and 60%). The behaviour of HVFAC was assessed by different strength properties at varying curing periods of 3, 7, 14, 28, 56 and 90 days. It is observed 50% replacement of steel slag shows better results when HVFAC was prepared with 40% fly ash, further increment of fly ash reduces the strength concrete irrespective of steel slag replacement percentage.
