Abstract: The safety to our ecosystem can be assured by making use of many industrial wastes in a sustainable manner. Recycling and reutilisation of industrial waste and by-products is of high importance in cement and concrete industry. In view of rapid infrastructure growth, there is an emerging need for development of cementitious materials or fillers either to replace cement or fine aggregate for stable growth. One of such industrial wastes is secondary aluminium dross. In this paper, an attempt has been made to study the mechanical properties of concrete incorporated with secondary aluminium dross. Portland pozzolana cement has been partially replaced by secondary aluminium dross in various proportions like 5, 10, 15, and 20% to study the mechanical properties such as compressive strength, split tensile strength, flexural strength, water absorption. It is observed that up to 15% replacement of cement by secondary aluminium dross is giving better results comparable with the conventional concrete. Also, the increase in initial setting time is observed with increase in percentage replacement of aluminium dross in the concrete which can make it preferable in case of hot weather conditions wherein the concreting for the roads has to be done in an open environment. From the overall study, it can be concluded that the concrete incorporated with secondary aluminium dross can be used for making pavement quality concrete that can sustain low traffic volume or it can be considered for rural roads. � 2019 American Society of Civil Engineers.
