“Experimental Investigation On Strength Characteristics Of Concrete With GGBS And Metakaolin”

Abstract: This study looks at how to make M30 grade concrete in a sustainable way by using less Ordinary Portland Cement and adding Ground Granulated Blast-Furnace Slag and Metakaolin. The goal is to reduce the impact that making traditional cement has on the environment without making the concrete weaker.The researchers are comparing a mix that is 100 percent Ordinary Portland Cement to three other mixes. One mix has 25 percent less Ordinary Portland Cement. Is replaced with 20 percent Ground Granulated Blast-Furnace Slag and 5 percent Metakaolin. Another mix has 35 percent less Ordinary Portland Cement. Is replaced with 25 percent Ground Granulated Blast-Furnace Slag and 10 percent Metakaolin. The last mix has 45 percent less Ordinary Portland Cement. Is replaced with 35 percent Ground Granulated Blast-Furnace Slag and 15 percent Metakaolin. They are testing the strength of these M30 grade concrete mixes at 7 days, 14 days and 28 days to see how strong they are. They are also testing how well the concrete can bend and stretch. The study wants to find the mix of Ground Granulated Blast-Furnace Slag and Metakaolin that is good, for the environment and still makes strong M30 grade concrete that can be used to build things. This will help us build in a sustainable way.
