Performance evaluation of marine and industrial wastes in cement to envelope low carbon environment in manufacturing process

Abstract

The bonding strength of waste recycled cement mortar in a low carbon brick masonry prism is influenced by this study. The disposal of marine and industrial trash has emerged as a serious environmental and ecological concern across the world against the climate action of the United Nations Sustainable Development Goals (UNSDGs) and COP27. The use of alternative waste materials in the cement industry minimizes the carbon footprint in the manufacture, construction and overall building lifespan and enhances low carbon technology. The bonding 1ehaveior of the 3R hybrid cement (oyster shell, ground granulated blast furnace slag and tyre waste powder) is evaluated in a brick masonry prism. The impact of hybrid mortar bond strength on triplet masonry prism specimens and cement mortar cubes is investigated in this study using first-class bricks and OPC 53 cement with 3R waste materials. In addition, the chemical characteristics, workability, compressive strength, shear, bond, thermal, durable and microstructure studies of traditional and hybrid cement composites were determined. These three waste material compositions in the cement matrix have an influence on the development of alternative waste recycling and reuse materials in industry. Using hybrid cement saves CO2 emissions, low carbon emissions and energy consumption and has economic and environmental implications. The testing findings show that the brick-and-mortar bond has an excellent lead with the maximum compressive strength of the brick masonry prism.
