DESIGNED CONCRETE SPECIFICATIONS - The Constructor

For example, class M30 (C25/30 as per British Standards) is the concrete having a characteristic compressive cube strength of 30 N/mm 2. The same concrete would have a characteristic strength of 25 N/mm 2 at 28 days if cylinders were used for testing, as in certain European countries.

Concrete Exposure Classes - Spartan Ready Mix

† The minimum specified compressive strength may be adjusted to reflect proven relationships between strength and the water -to-cementing materials ratio. The The water-to-cementing materials ratio shall not be exceeded for a given class of exposure.

Effect of aggregate type on Compressive strength of concrete

The compressive strength of concrete depends on the water to cement ratio, degree of compaction, ratio of cement to aggregate, bond between mortar and aggregate, and grading, shape, strength and size of the aggregate (Roccoand Elices, 2009; Elices and Rocco, 2008).

Compressive Strength of Concrete Cubes - Civilology

Overall Strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days.

Properties of concrete - Wikipedia

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.
