Nov 16, 2022· The solution to this problem can be the use of fine-grained concrete, however, its strength characteristics can be significantly lower than that of heavy concrete with the use of a large aggregate acting as a skeleton. Thus, fine-grained concrete, with all its technological advantages, has significant design and operational disadvantages [1,2,3,4].

For establishing a relation between core strength and standard cube strength, ratio of l/d = 2.0 is taken as the basis of computation. Factor # 3. Diameter of Core: The diameter of the core may influence the measured strength and variability. Measured concrete strength decreases with the increase in the size of specimen. This effect is significant.
