A method of producing green concrete, and particularly to green concrete with Portland cement (C), natural basaltic volcanic ash pozzolan (VA), and microsilica (MS). The green concrete described herein is a high-performance green concrete composition that partially substitutes Portland Cement (C) and can further include fine aggregates (FA) and coarse aggregates (CA), water (W), and a super plasticizer (SP). The green concrete described herein can be cured at ambient temperature and can have a better compressive strength and durability properties, and high shrinkage resistance as compared to conventional concrete and, as such, can be used for high performance applications.
