The proportions of cement, aggregate, sand, and water in a concrete mix can vary depending on the specific application and desired properties of the concrete. A common proportion for general construction is 1:2:3 (cement : aggregate : sand) by volume, with water added to achieve the desired consistency. In terms of weight, this would be approximately 75% aggregate, 15% cement, 10% sand, and 5-10% water. For the given mixes (M10, M15, etc.), the proportions may be slightly different based on the size of the aggregate particles and other factors.
