Excessive usage of cement increases dust concentration around the construction project which contributes to severe surrounding air pollution and adverse health effects. Therefore, this study was conducted to investigate the potential of pozzolanic material as admixture to partially replace cement in concrete as a mean of producing more environmental friendly cement products. The content of fly ash as partial replacement of ordinary portland cement is investigated by weight. The workability of the fresh concrete mixtures was evaluated using slump test while compressive strength of cubes concrete were evaluated at 7, 14 and 28 days. The optimum compressive strength at all ages of testing was obtained at 10% replacement. Workability decreased with an increased in replacement percentage of fly ash. The results therefore shows that fly ash as pozzolanic materials ca...
