· 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 .
Concrete BlockBackgroundA concrete block is primarily used as a building material in the construction of walls. It is sometimes called a concrete masonry unit (CMU). A concrete block is one of several precast concrete products used in construction. The term precast refers to the fact that the blocks are formed and hardened before they are brought to the job site.

The compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. The compressive strength is calculated from the failure load divided by the crosssectional area resisting the load and reported in units of poundforce per square inch (psi) in US Customary units or megapascals (MPa) in SI units.
· Compressive Strength Test Idea: 1 Concrete is poured in the mould and compacted properly to reduce the amount of voids. 2 After 24 hours, moulds are removed and test specimens are then placed in water for curing. 3 After the specified curing period [3, 7, 28, 56, or 91 days], specimens are tested by the compression testing machine.
· Cons: This test involves crushing or damaging the concrete. A large number of test samples are needed at different loions of the slab for accurate results. 5.
Several variables contribute to define the quality of the concrete utilized for a structure: workability, consistency, setting time and air content are only few examples. Matest proposes a wide range of testing equipment and high stiffness compression machines (manual, semi automatic or automatic) which allow to test concrete cubes, cylinders ...
Types of Concrete Blocks. Mainly there are two types of concrete blocks depending on how they look like other than the mechanical properties. Solid Blocks. Normally blocks have a rectangular solid shape. Usually, they are available in widths 100mm, 125mm, 150mm, and 200mm. Hollow Concrete Blocks.
Concrete cubes may get crushed on one side or will develop tensile crack on one or more faces and fail. Fig shown below shows some of the likely unusual failures of concrete cubes. This type of failure will give lower indiion of compressive strength of concrete. These are usually due to defects associated with testing machine.
Concrete cube tests are performed to determine the compressive strength and other overall characteristics of concrete. In this destructive testing method, concrete cubes are crushed in a compression testing machine. The cubes used in this test have a dimension of 150 x 150 x 150 mm provided the largest aggregate does not exceed 20 mm. more ».
