EVALUATION OF THE POTENTIAL USE OF EGGSHELL POWDER AS PARTIAL REPLACEMENT OF CEMENT AND NATURAL CORN FIBER AS ANADDITIVE IN CONCRETE

The primary objectives of this research is to develop a suitable mix design to achieve high strength concrete by replacing cement with eggshell powder and addition of corn fiber as an additive. This study aims to understand the effect of using egg shell powder and corn fiber in concrete production in construction works. This methodology used for the development of high strength concrete through partial replacement of cement with eggshell powder and corn fiber as an additive entails using a methodical approach which includes using a suitable mix design and conducting series of tests on the concrete, these tests include: slump test, sieve analysis, aggregates impact value test, specific gravity test, durability test, compression test and flexural test on the concrete. As seen in the research work, there was a noticeable but minute decrease in the slump as the replacement % increases , an increase in durability as the eggshell powder % increases for 5% and 10% but reduced by 15% replacement, there was also an increase in the compressive strength for the 5% and 15% replacement concrete with 5% having the highest strength but a decrease in strength occurred in the 10% replacement concrete. It was also noted that the flexural strength of the concrete increased as the replacement % increases with 10% having the highest strength.
