Why Concrete Cubes shows greater strength than cylinder?
Concrete cubes typically exhibit higher compressive strength compared to cylinders at 28 days due to a few factors: Shape Effect: Cubes tend to distribute stress more evenly than cylinders. The corners of cubes experience higher stress concentrations, which can lead to higher ultimate strength compared to cylinders. Additionally, the failure plane in cubes is often through the center, which is a more direct path compared to the inclined failure plane in cylinders. Sample Preparation: Cubes are easier to manufacture and handle during casting and curing, resulting in more consistent and uniform specimens. Cylinders, on the other hand, are more prone to variations in casting and curing conditions, leading to potential differences in strength. Concrete cube and cylinders Surface Area-to-Volume Ratio: Cubes have a smaller surface area-to-volume ratio compared to cylinders of the same volume. This means cubes lose less moisture during curing, resulting in better hydration and potentially
