The compressive strength of concrete is one of the factors, which controls the loads, which may be applied to a concrete structure.Therefore, for every significant structure it is important to check the compressive strength from a representative number of concrete cylinders cast from the same batches of concrete used to form the structure.
View AllMolds for forming concrete test cylinders vertically must conform to astm c470.Cylinders made in accordance with astm c31 can be tested to failure in the vertical position for compressive strength astm c39 or instrumented and tested for modulus of elasticity and poissons ratio astm c469.
View All5.1 care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials.Values obtained will depend on the size and shape of the specimen, batching, mixing procedures, the methods of sampling, molding, and fabrication and the age,.
