Compressive Strength Test (ASTM C 39) - tpub

Compressive Strength Test (ASTM C 39) The compressive strength of hardened concrete is determined from compression tests on standard cylindrical specimens. As you know, compressive strength tests are used during concrete mix design to evaluate the performance of the materials and to establish mixture proportions that will give the required strength. The tests are used also to control the quality of the

Experimental Study on Improving the Compressive

The compressive strength of the material can be improved to some extent by changing the water-cement ratio, the proportion of each component of the material, and the curing method; however, the effect is negligible [6–8].Therefore, a method to improve the compressive strength of a cylindrical turntable by imposing external constraints is proposed in this paper.
