Compressive strength Wikipedia
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart).

What is a Compressive Strength? Definition from
05.02.2015· Compressive strength is a limit state of compressive stress that leads to failure in a material in the manner of ductile failure (infinite theoretical yield) or brittle failure (rupture as the result of crack propagation, or sliding along a weak plane). Compressive strength is measured on materials, components and structures.

As do most load bearing building materials, EPS foam insulation products creep under long-term, continuous load conditions and, in critical applications, this characteristic must be considered in design calculations. Design professionals
6 Ways You Know to Test Concrete Strength and 1 You
Pros: Compressive strength data is given in real-time and updated every 15 minutes. As a result, the data is considered more accurate and reliable as the sensors are embedded directly in the formwork, meaning they are subject to the same curing conditions as the in-situ concrete element. This also means no time is wasted onsite waiting for results from a third-party lab.
