Physical, mechanical and durability properties of sugarcane ash enhanced compressed earth blocks stabilized with fly ash and lime powder

description: The construction sector is one of the principal component of anthropogenic activities and a major contributor of greenhouse gases (GHGs) emissions. Large quantities of solid wastes are being produced every year by industrial and agricultural industries which lead to environmental and health concerns such as flooding, air pollution and other public health scarce. These wastes have potential pozzolanic reactivity and may be used to develop cementitious materials that are sustainable, while maintaining requirements as affirmed in various standards. The sector is also an important economic sector that has a large environmental impact in terms of large quantities of construction and demolition wastes (C&DW) which are generated. These is mainly due to severe shortage of natural aggregates (NA) for the production of new concrete materials, and a boom in construction activities currently taking place worldwide. The utilization of recycled masonry and concrete (RCA) from C&DW will conserve the natural resources and reduce the environment impact of concrete manufacturing. Sugarcane bagasse ash (SCBA) is an industrial waste material obtained from sugar milling industry that can be used as pozzolanic material for the development of greenbricks. In this research, the application of various waste materials and the effects of fly ash and lime on the mechanical and durability properties of compressed earth bricks (CEBs) are investigated. Secondly, the applications of fly ash, recycled cement and masonry as industrial waste materials in construction industry are reviewed. Lastly, The SCBA greenbricks were developed using lime as a chemical stabilizer and tested for physical, mechanical and durability properties. In addition, several agricultural by-product such as sugar cane bagasse (SCB) and soft wood (SW) were treated as wastes until recent times when researchers considered incorporating them in polymeric matrices to mainly avoid environmental pollution and cost of a new synthesis…
