Effect of Corn Cob Ash on Fresh and Mechanical Properties of Concrete: A Systematic Literature Review

Abstract

In this research review, the effect of corn cob ash (CAA) as a cement replica- is figured out critically on fresh as well mechanical properties of concrete. These review integrates outcomes on workability, compressive strength, and flexural strength of CAA mixed concrete, while taking structured inspection of peer evaluated probing published between 2009 and 2023. The review comes out with the fact that although CAA blended concrete exhibits pozzolanic aptitude yet particle size and replacement level effects accordingly on fresh and mechanical properties. Requisite replacement levels generally fall within range of 5% to 15% but higher levels often result in reduction of strength. This paper pins downs notable research interval in long term strength analysis along with conformity of CAA manufacturing protocols, while recommending upcoming research directives for the utilization of this sustainable agricultural waste in concrete manufacturing.
