How to Order/Specify Concrete. Here's how most people order concrete: Call the concrete contractor and tell him they want a new driveway, porch, sidewalk, foundation, or slab.
Compressive Strength 2015 Concrete Manual 25
In the early 1970s, experts predicted that the practical limit of ready-mixed concrete would be unlikely to exceed a compressive strength greater than 11,000 pounds square inch (psi).
Concrete Quality Testing. The quality of concrete can be assessed from its penetrability, density, elastic properties and modulus of concrete. Ultrasonic pulse velocity is able to give information on density and elastic properties of a material which can be further translated into the quality of the material.

Concrete has relatively high compressive strength, but significantly lower tensile strength.As a result, [further explanation needed] without compensating, concrete would almost always fail from tensile stresses – even when loaded in compression.
As recently as 25 to 30 years ago, the steadily increasing availability of concrete with compressive strengths above 6,000 psi had the industry's rapt attention. Back then, in many regions, strengths this high were considered revolutionary. Some people even questioned the need. Fast forward to ...
Concrete is a construction material composed of cement, fine aggregate (sand) and coarse aggregate mixed with water which hardens with time. Portland cement is the mostly used type of cement for production of concrete.

PCC is most often known by its compressive strength. This is because PCC is much stronger in compression than it is in tension and thus, is often used in compression. The ACI Concrete Code gives some rough rules-of-thumb for converting compressive strength to tensile and flexural strength:
The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete design, construction, and materials, who share a ...
The specification for the floor of a maintenance building called for a 6-inch slab thickness and concrete with a design compressive strength of 3000 psi. The actual average cylinder strength for the floor concrete was 3630 psi.
