Curing of concrete nscp
WebStudies indicate that traditional concrete’s tensile strength varies between 300 and 700 psi, i.e., around 2 to 5 MPa. This means, on average, the tension averages about 10% of the compressive strength. Flexural Strength Of Concrete. Flexural strength establishes the ability of concrete to withstand bending.

WebRounded off it's basically a 1 : 3 : 3 mix ratio. If I break the weights down per yard of concrete it comes to: 1. Cement = 510.75 pounds. 2. Stone = 1658.75 pounds. 3. Sand = 1496.25 pounds. A sack or "bag" of cement weighs 94 pounds so this tells us a 3000 psi concrete mix is also equal to a 5.5 sack mix of concrete.
