When tested, a 15 cm cube concrete specimen showed lower compressive strength compared to a 10 cm cube specimen of the same mix. This can be explained by Select one: O A. The 15 cm cube specimen probably can containa greater number of critical cracks. O B. The compaction of the 15 cm cube specimens is usually harder than the compaction of the 10 cm cube specimen. OC. The 15 cm cube specimens has more aggregates. O D. Segregation is more probable to occur in the 15 cm cube specimen.
