COMPRESSIVE STRENGTH OF CONCRETE CUBES
· Compressive strength of concrete: Out of many test applied to the concrete, this is the utmost important which gives an idea about all the characteristics of this single test one judge that whether Concreting has been done properly or not. For cube test two types of specimens either cubes of 15 cm X 15 cm X 15 cm or 10cm X 10 cm x 10 cm depending upon the size of .

Mechanical Performance of Concrete Made with Recycled ...
· This research aims at analysing the mechanical performance of concrete with recycled aggregates from concrete pavements. First, the characteristics of various natural and recycled aggregates used in the concrete were thoroughly analysed. The composition of the recycled aggregates was determined and several physical and chemical tests of the aggregates were performed.

StressStrain Behaviour of Concrete
The stressstrain behaviour in tension is similar to that in compression. The descending portion of the stressstrain curve, or in other words, the postpeak response of the concrete, can be obtained by a displacement or a strain controlled testing machine.

What would the values C30/37 mean, in concrete mix design ...
Answer (1 of 5): Concrete can be specified by its constituents, or by the properties of the hardened concrete. The C30/37 refers to the crushing strength of a sample of the concrete at 28 days after it was mixed. There is a European Standard BS EN 206 on the specifiion of concrete. BS 8500 ...

Compressive strength in concrete test
· COMPRESSIVE STRENGTH • Compressive strength is the capacity of a material or structure to withstand axially directed pushing forces. • When the limit of compressive strength is reached, brittle materials are crushed. • The compressive strength is used to determine the hardness of cubical and cylindrical specimens of concrete. 3.
