ABSTRACT: In this paper, researchers studied and developed waste management strategies to apply for advantages for specific needs. Owing to the scarcity and harmful of cement for the preparation of mortar and concrete, partial replacement of steel Slag with M-sand have been attempted. The effects of replacing cement by steel slag on the compression strength of cubes, split tensile strength of cylinders and textural strength of beams are evaluated in this study. steel slag is obtained as waste product from the sterlite industries. Investigations were carried out to explore the possibility of using steel slag as a replacement of cement in concrete mixtures. The test results of concrete were obtained by adding steel slag to cement in various percentages ranging from 10%, 20%, 30%.All specimens were cured for 7 days, 14 days and 28 days before compression strength test, splitting tensile test and flexural strength. This results of the research paper showed that the possibility of using
STAIRCASE Staircases provide means of movement from one floor to another in a structure. Staircases consist of a number of steps with landings at suitable intervals to provide comfort and safety for the users. Some common types of stairs are These include straight-flight stairs, quarter-turn stairs, half-turn stairs, branching stairs, and geometrical stairs.
