    This study has shown that pozzolan made from corn cane ash is an effective material for improving the properties of concrete. The results obtained have shown that the addition of this pozzolan in an adequate proportion can significantly increase the compressive strength of the concrete. Through the experimental study, it was observed that the addition of 6 percent corn cane ash to concrete produces a greater compressive strength after 28 days, reaching a value of 230.98 kg/square centimeters. However, it has been detected that, by increasing the proportion of pozzolana above this value, the strength of the concrete decreases significantly. In addition, it was proven that concrete mixtures with corn cane ash pozzolana meet the requirements of plastic consistency and workability. The de nsity obtained for all mixtures exceeds the minimum value established by the ACI 318 19 standard. In summary, this study has demonstrated the effectiveness of corn cane ash pozzolana to improve the properties of concrete, and its use in construction is recommended to obtain high strength and quality concrete. The use of corn cane ash pozzolana in construction obtained additional benefits, such as reducing the carbon footprint and promoting sustainability. Corn cane ash is an agricultural waste that is generated in large quantities, and its use as a pozzolana can help reduce the amount of waste sent to landfills; It is also a cheaper and more accessible alternative to traditional pozzolans, which can be beneficial for the construction industry. Importantly, although the results of this study are promising, further research is needed to determine the feasibility and effectiveness of corncane ash pozzolana in different applications and conditions. However, the results obtained in this study suggest that this additive is a material with great potential to improve the properties of concrete and promote sustainability in construction.
