Study of Strength of 3 D Printable Concrete by Partial Replacement of Quartz Powder by Steel Slag

Abstract

3-D concrete printing is an emerging technology that combines digital technologies and new insights from material technologies to allow free-form construction without the use of frame work. Conventional construction methods have many limitations because which has shown remarkably poor productivity as compared to other sectors in the economy. With the discovery of printable concrete most of the limitations conventional concrete construction can be solved. Our idea is to develop a printable concrete mix by incorporating steel slag which is a waste material from steel industry. Construction using 3-D concrete printers has not been started yet in India, but it had been successfully done in many other countries. Construction using 3-D concrete printer can overcome many of the problems faced by conventional construction. But the technology is not fully developed since there is no specification for the mix in the Indian Standard. We aim to develop a low cost concrete mix to make it more affordable than the one available in the market presently.
