“…ISO 14000 helps to reduce adverse environmental impact through the life of product or service. ISO 14000 includes ISO 14040 -ISO 14043 as a key standard for life cycle assessment [17].…”
A rapid industrialization and urbanization resulted in the increased demand for usage of electricity at an alarming rate. At the same time, coal ashes are produced in coal based thermal power plant in large quantity. Fly ash is being used as an alternative material in construction industries while pond ash is disposed-off on huge land areas resulting in environmental pollution through soil, water and air. This research emphases on the study of performance of pond ash as a fine aggregate in self-compacting concrete (SCC). Fine aggregate is substituted by pond ash in percentages of 10, 15, 20, 25, 30. The fresh state properties of SCC like flowability, passing ability of all mixes have been checked by conducting inverted slump cone and L-box according to IS code of practice. The cost analysis of SCC has been conducted to establish the relative cost savings. From the experimental investigation, cost analysis and life cycle assessment, it is concluded that SCC with 20% fine aggregate replaced by pond ash can be economical and environment friendly self-compacting concrete.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
