Strength Behaviour of Masonry Blocks Produced Using Green Concrete
Increased search for sustainable and eco-friendly construction materials has led to research on the development of new materials using industrial by-products or waste materials and new technologies. Partial or complete replacement of constituent materials of conventional cement concrete has been tried by different researchers depending on the availability and relative cost of industrial waste materials. On taking into consideration of the above facts, an investigation was planned to study the effect of complete replacement of Portland cement by using fly ash and GGBS, based alkali activated cement in producing standard solid masonry blocks of size. In the study, a complete replacement of conventional river sand by locally available quarry dust was also made. The compressive strength and tensile strength of masonry blocks have been studied as per IS 2185-1-2005. The results have shown that the alkali activated concrete masonry blocks utilizing quarry dust will reduce the cost of the block without compromising the strength and durability properties.

All masonry blocks were prepared in the new research laboratory of the Civil Engineering Department, NMAM Institute of Technology, Nitte. Authors wish to express their gratitude to the authorities of these institutions for the permission and encouragement provided during the investigation. Financial support provided by Nitte Education Trust, i.e., NMAMIT research fund on the project entitled “Study and to Develop Cost Effective and Green Masonry Block Using Industrial Waste Materials” is gratefully acknowledged.
