Experimental Study Of Physical, Fresh-state And Strength Parameters Of Concrete Incorporating Wood Waste Ash As A Cementitious Material

Résumé: The increasing demand and production of cement have caused a huge environmental burden and thus researchers are involved in discovering waste materials having cementitious properties to reduce the production and usage of cement in order to contribute towards the development of a sustainable environment. The present study, therefore, sought to quantify the influence of wood waste ash (WWA) as a cementitious resource on the fresh-state, physical, and strength parameters of concrete. The water absorption, workability, density, compression strength, tensile strength, and flexural strength of concrete was checked at various replacement levels i.e. 0%, 5%, 10%, 15%, and 20% by weight fraction of cement. The density and water absorption were checked on the 28th day of curing while the strength parameters were tested at 7, 28, 56, and 90 days of curing period. The water absorption, density, and workability of concrete reduced with an increase in wood waste ash content while the strength values were increased up to 10% replacement level. Hence, this study suggests that 10% WWA can be used instead of cement for concrete structures.
