ConCrete Sampling and teSting - Precast concrete

concrete cylinders is to determine the amount of force it takes to break a cylinder of concrete. A test cylinder is placed in a compression-testing machine, and a constant load is applied to the cylinder until it breaks. The compressive strength is calculated based on the applied load and the size of the test cylinder.

What Test-Cylinder Fracture Types Indicate| Concrete ...

I've heard that the two-cone fracture pattern is typical when compressive-strength cylinders are tested. Does that mean any other fracture pattern indicates a testing or concrete problem? Figure 1, from ASTM C 39, "Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens," shows some of the other possible fracture types.
