Compressive Strength Test of Concrete
06/03/2017 · Compressive strength as a concrete property depends on several factors related to quality of used materials, mix design and quality control during concrete production. Depending on the applied code, the test sample may be cylinder [15 cm x 30 cm is common] or cube [15 cm x 15cm x 15 cm is the most common].
