Abstract: Incineration is the treatment process of waste material by combustion of inorganic substances present in the waste materials. The obtained bottom ash is a material with great potential to be used in cementitious products as partial cement replacement. Incinerator ash was investigated for its potential use as a replacement for cement in concrete. The physical and chemical characteristics of the raw materials were determined. Mixes were prepared, incinerator ash was used at 0%, 15%, 20%, 25% and 30% replacement by weight for cement while sand and water quantities were kept constant. The cement, sand and aggregate mixing proportions were 1:1.5:3, respectively. Consistency tests, Initial and final setting time, specific gravity test and fineness test were performed on cement, And Slump cone test and Compressive test were performed on concrete.Mortars were prepared according to Indian Standard IS-10262-2019 Specimens were compacted in three Layers using a tamping rod . After 24 h, specimens were Removed from the moulds and submerged in a water tank For testing at 7and 28 days. Twenty four cubes ( 150mm × 150mm × 150 mm ) were prepared for each Incinerator ash content (three samples for each curing Period) for compressive strength Determination. A total of 30 cubes were tested in this Study. The physical tests performed on the mortar samples Include slump, compressive strength. The control specimens containing 15% ash have a Compressive strength of 22.1 Mpa after 7 day of curing.
