Abstract
Abstract The supplementary or alternative material to cement has been an emerging field in civil engineering. The concrete ingredients have become modern due to the need for reducing global warming and material scarcity problem. Fly ash is used to replace cement partially in concrete, therefore the concrete mix has changed their characteristics as obtained by normal concrete. The proper investigation always required for performance measurement and to measure the fresh concrete property, the slump cone test, and compaction factor test are the tool. The Slump Test has become the most frequently performed due to the practicality of the recommended equipment and the experiment protocol. The slump test involves the cone’s behavior under the action of gravitational forces. The slump check is a realistic way to gauge the workability. The concrete slump test and compaction factor test are used to determine the consistency of fresh concrete before it sets. This paper has focused on testing the 54 mixes having various water-cm ratios like 0.5, 0.55, 0.6, 0.45, and 0.4. Fly ash material possesses satisfactory workability properties due to their similar oxide compositions. Due to the fineness of fly ash, less bleeding observed than control concretes.
