Concrete Cylinder Compression Test: Evaluating Strength
Concrete's compressive strength is crucial for structural evaluation and design and factors such as load-bearing capacity. If your design is residential, the strength can range from 2500 psi (17 MPa) for residential concrete to 4000 psi (28 MPa). The required strength is higher for commercial structures.

Compressive (Strength) Values of Pool Shotcrete
The resulting structure's concrete porosity and resulting compressive strength will easily exceed 4000 psi (27.6 MPa) using the shotcrete (wet) process. Further, due to cement content and lower w/cm inherent in dry-mix (gunite) shotcrete, concrete compressive strengths will normally far exceed the 4000 psi

Comparison of Strength and Construction Tolerances in Concrete
On this basis, the investigation found that a strength tolerance of 0.90 f c is a more consistent representation of allowable concrete strength variation than f c- 500 psi (3.4 MPa). While this approach is not sufficient by itself, it does indicate that the 0.90 f c criteria is a more rational approach to compressive strength tolerance.
