Concrete is a building material made from a mixture of cement, water, sand and gravel. Known for its strength and durability, concrete is used to construct buildings, bridges and roadways. To ensure a concrete structure will last, inspectors test the strength of the concrete once it has had time to dry.
Supplied in the form of either Concrete with 4-20mm stone, or Mortar, without stone. Each mix additionally consists of cement, graded sand and water. The mix has a ing agent added which entrains air in to the concrete to give high workability and levelling properties, achieving 4 …
C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100mm concrete cylinder and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube. Therefore using the method of testing using concrete cubes, the tested compressive strength should be compared to …
The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C15 means that the concrete will have a compresion resistance (withstanding a compression) of 15 N/mm2 per square millimetre in 28 days.

Mortars and concrete are the fundamental components of much of the construction industry in Britain and Ireland. For everyday definition purposes, a concrete is a cementitious material containing aggregates of sizes greater than 5 mm, whereas a mortar is a cementitious material containing aggregates of sizes less than 5 mm.
design of concrete structures and in table 3.1 gives recommended values for various mechanical properties of concrete for use in design. These property values are based on a number of assumptions and in general will be conservative. In most cases, these design values will be appropriate; however, in some circumstances the assumed design value may
The proposed mean concrete strength is well within Priestley recommended lower- and upper-limits. Certainly, if more concrete test data from various public and private projects is available, more reliable mean strength prediction formulas covering full range of concrete grades can be obtained.

Concrete mixes are measured in grades which are calculated in newtons per square millimetre. For example a C25/30 is required to reach a compressive strength of 30 newtons after twenty eight days. Strengths can range from 10 newtons through to high strength concrete mixes at 50 newtons. source: C25 | Concrete mix
