Only 125 years' worth of lime stone is anticipated. The main issue is how the construction will go in the future. The partial preservation of the concrete material is crucial. In this initiative, coffee husk ash (CHA) is being used to partially replace cement. 60% of the silica in coffee husk, which is useful for binding, is present. Small amounts of SiO2, Al2O3, and Fe2O3 make up CHA, whereas Cao makes up a larger portion. Due to the silica (SiO2) and aluminate content, coffee husk ash functions as a pozzolanic material when added to cement. This reaction between the free lime produced during the hydration of the cement and the reaction material results in the formation of extra calcium silicate hydrate as a new hydration product. From environment point of view, when Coffee Husk is dumped in factories it produces green house gases such as methane, carbon dioxide etc. which threatens the environment and imparts Global warming. The main objective of this project is to conserve cement and provide better settlement of agriculture waste. Based on the primary objective of this research, the laboratory tests were designed to obtain the strength of concrete specimens with partially replacement different percent of coffee husk ash under different types of loading. Three types of tests were performed- the compressive strength test, compression factor test, and slumps test.
