Properties of Mortar Incorporating Iron Slag

Abstract

Iron and steel slags are byproducts of the iron and steel industry. They are used not only in construction and road building, but also in other ways such as in waste stabilization. Slags are used in road bases, various types of concrete aggregates, fill, glass manufacture, mineral wool, railroad ballast, and soil conditioning. Research during the year emphasized blast furnace slags incorporated into blended cements, and used in oil well drilling, and waste stabilization, as well as various uses of steel slags. Total slag consumption increased by 6%,partly due to increased demand for slag in the construction industry and increased quantities of slags available. Domestic consumption of reported iron slag stayed the same when compared with that of 1993, while the consumption of reported steel slag increased by 17%.. In the present study effected iron slag as fine aggregate replacement on compressive strength, split tensile strength, sulphate resistance, RCPT Test of cement mortar having mix proportion 1:3 .Fine aggregate were replace with five percentage of iron slag. The percentages of replacements were 0.10, 20, 30, and 40% by weight of fine aggregate. Test were performed for compressive strength, split tensile strength, sulphate resistance, RCPT Test .Test for all replacement levels of iron slag at different curing periods (7, 28, 56 days ). Test result indicates that inclusion of iron slag as partial replacement with fine aggregate enhances the properties of concrete.
