STRENGTH, DURABILITY AND TOUGHNESS OF STEEL SLAG CONCRETE

This paper presents a study aimed at investigating the strength, durability and toughness properties of steel slag on complete replacement as fine aggregate and compared with the results of other fine aggregates such as natural river sand and crushed stone sand for Concrete Pavement Quality (CPQ) as per Ministry of Road Transport and Highways (MORTH). For this study M40 grade of concrete with 100% replacement of high volume steel slag is utilized. Quality is determined from experimental test values. The material properties were carried out experimentally, according to material properties compressive strength, flexural strength, durability test such as water permeability test and RCPT test are carried out and also toughness property is studied by the addition of steel fibers to steel slag concrete. The results showed that steel slag sand values are well within the limits of MORTH and hence can be used as pavement material.
