teC noteS ConCrete Sampling and teSting T he sampling and testing of concrete is a common step in the production process. Samples are taken during production
testing the compressive strength of concrete, cylindrical test speci- mens of size 4 × 8-inch (100 × 200-mm) or 6 × 12-inch (150 × 300- mm) are cast and stored in the field until the concrete hardens in
2006-03-24· Best Answer: There are several types of tests for testing the strength of concrete in various ways but the most common is the compressive testing. ASTM C 31/ C31M-03 allows for three different sizes of cylinders (first number is diameter): 4"x8" (100mm x 200mm), 6" x 12" (150mm x 300mm), and 9" x 18" (225mm ...
Compressive Strength. The compressive strength of any material is defined as the resistance to failure under the action of compressive forces. Especially for concrete, compressive strength is an important parameter to determine the performance of the material during service conditions.
Procedure for compression test of concrete Clean the cylinder mould and coat the inside lightly with form oil, then place on a clean, level and firm surface, ie the steel plate. Collect a sample.

Compressive Strength of Concrete Cubes – Lab Test & Procedure 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.
Procedure: Compressive Strength Test of Concrete Cubes For cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical moulds of size 15cm x 15cm x 15cm are commonly used.

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
Concrete cube testing as with all methods of testing, fresh / hard concrete are governed by standards set by the British Standards Institute and or the client in-house specifications. These standards specify all aspects involved in the process of carrying out tests, from the equipment to the method of testing.

The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.
3.1 This test method provides standardized procedures for obtaining and testing specimens to determine the compressive, splitting tensile, and flexural strength of in-place concrete. 3.2 Generally, test specimens are obtained when doubt exists about the in-place concrete quality due either to low strength test results during construction or signs of distress in the structure.
