Abstract
Road Construction is an activity in which natural resources are used the most in comparison with else branches of Civil Engineering. Prominent quantities of natural materials, stone, rocks and sand are built into kilometres of roads or in reconstruction of frail roads. This paper presents the basic characteristics of slag, describes several of established investigate studies carried out so far, and analyses domestic experience and the possibilities of application of slag in road constructions. To solve the problem of greenhouse gas emission from industries we can reuse the wastes from industries and help environment. The effective manner is to use slag in concrete by replacing natural coarse aggregate. In this study, the replacement was done with coarse aggregate by steel slag for different proportions of 0%, 25%, 50%, 75% and 100% for a M30 grade of concrete is used for a water cement ratio of 0.48. Tests for compressive strength at 7 days, 14days and 28 days are conducted on specimens. Split tensile strength and flexural strength are carried for 28 days. The optimum strength is obtained on 75% replacement of coarse aggregate by steel slag.
