In this paper the detailed experimental investigation was done to study the effect of partial replacement of cement and fine aggregate in combined proportions started from 8% Rice Husk Ash (RHA) with partial replacement of cement and 4% of Brick dust kilin with replacement of fine aggregate in concrete mix.In mix two RHA was was gradually increased by 15% by weight of cement and Brick dust kilin increased by 8% by weight of fine aggregate . Last porportion was taken 30% of Rice husk ash and 16% of Brick dust kilin.The tests on hardned concrete were destructive in nature which includes compressive test on cubes for size ( 150 x 150 x 150mm ) at 7,14,and 28 days of curing as per IS :516 1959.Flexural strength on beam (150 x 150x700mm) at 28 days of curing as per IS:516 1959,and split tensile strength on cylinder (150 x 150x300mm) at 28 days of curing as per IS 5816 1999.The experiment presented in this paper reports the effects on the behavior of concrete produced from cement with combination of Rice husk ash and Brick dust kilin at different proportions on the mechanical properties of concrete such as Compressive strength ,Flexural strength, and Split Tensile strength.Investigation reported that compressive strength increases by 17.5%in compared with targeted strength and reduces by 2% compared with control concrtete at 28 days, flexural strength increases by 2.86% compared with control concrete at 28 days, split tensile strength decreases by 11% compared with control concrete at 28 days,were obtained at combination of 15% Rice husk ash and 8% Brick dust kilin.Partial replacement of Rice husk ash and brick dust kilin reduces the environmental effects,produced economically and eco friendly concrete.
