Abstract - As In the recent decades the worldwide construction business has encountered hurdles owing of the Covid-19 epidemic, resulting to developing concerns. Material shortages throughout the supply chain have become a serious problem. Construction material contributes about 50% of overall project expenditures. Effective material management is vital to solve shortages and limit inventory costs. The continued demand for building services leads to increasing costs. Sustainable building materials serve a crucial role in resolving environmental issues and boosting resilience in civil engineering projects. The easiest technique to handle this problem is include the waste products towards elements in concrete. COFFEE HUSK ASH (CHA) is a byproduct obtained from the burning of coffee husks, which are produced in vast amounts owing to worldwide coffee bean trade. Researchers have examined the use of CHA in concrete, particularly as a partial cement substitute. However, our experimental work, the emphasis moved to replacing fine aggregate (not simply cement) with CHA. CORN COB ASH (CCA) is another agro-waste resource that may be utilized as a supplemental cementitious ingredient. It helps lessen the environmental effect of concrete manufacturing and may be partly replaced for cement.
This Paper speaks about preserve the consistent frequency to compose CCA with cement 4% & CHA with Fine total like 0%, 3%, 6%, 9%, 12% & 15% and additionally the comparison is conducted with proxy blends like 0%CCA+0%CHA, 4%CCA+3%CHA, 4%CCA+6%CHA, 4%CCA+9%CHA, 4%CCA+12%CHA & 4%CCA+15%CHA for M40 Specific. In summary, both coffee husk ash and corn cob ash provide viable solutions for strengthening concrete characteristics while resolving waste management problems. This study continues to seek creative methods to employ such materials in sustainable building processes.
