Another major reason craftsmen regularly use concrete mix ratios is to achieve a certain tensile strength from the resulting concrete. Before continuing, though, you should also make sure you understand the differences between concrete, mortar, and other similar materials. Though it is on the lower end of the concrete strength scale, this mix ratio actually requires larger amounts of certain key ingredients. the differences between concrete, mortar, and other similar materials.

Different Water-cement ratios are utilized for different concrete applications.For high-quality concrete construction, a lower water-cement ratio of 0.4 could be employed. cubic feet. Normal compressive strengths when concrete is properly cured are: 0.4 w/c ratio –> 5600 psi; 0.8 w/c ratio –> 2000 psi. The sand tends to make the concrete a little more easier to work with.
