USABILITY AS A POZZOLAN IN CONCRETE PRODUCTION OF NUTSHELL BRIQUETTE ASH

Abstract

The depletion of traditional energy sources and environmental problems have increased the orientation to new and renewable energy sources. In this context, studies have intensified on the use of wastes generated in different sectors for energy production. As a result of these studies, fuel briquettes were produced from hazelnut shells and put into use for heating purposes in different structures. In this study, it was aimed to prevent environmental problems caused by the ash formed as a result of burning the briquettes produced from hazelnut shells and to investigate its usability as a pozzolan in the production of economical and durable concrete with high insulation properties in the construction sector. In this way, it will be possible to convert ash, which is the waste of a useful product produced from an agricultural waste, into a product with high added value in the construction sector. For this purpose, the effects were investigated on the physical, mechanical and thermal properties of concrete of using briquette ash in different proportions (0, 5, 10, 15 and 20%) as a substitute for cement in concrete production. As a result of the research, it is recommended to use briquette ash up to 5% in order to produce concrete with sufficient strength and good insulation, as it is possible to use briquette ash as a pozzolan in concrete production.
