Concrete testing methods vary by location, and each country has its own characteristics that must be followed. While engineers and project managers in America adhere to the American Standard Test Method (ASTM) C39 / C39M, Standard Test Method for Compressive Strength of Cylindrical Concrete Samples, European residents comply with the EN 12390-Compressive Strength Test in Hardened Concrete standard.
Concrete Cube Sample Breaking Test
Concrete cube specimen breaking test is also done to determine the compressive strength of a concrete.
The dimensions of the cubes used for this experiment are 150 x 150 x 150 mm as long as the largest aggregate does not exceed 20 mm.
Generally speaking, cubes are cured and tested in 7 and 28 days, but some projects may require curing and testing times of 3, 5, 7, 14 or more days.
The results obtained from the compressive strength test are used to determine the strength of concrete. If test results are unsatisfactory or show that your concrete is not curing as quickly as it should, you risk not progressing your project as well as you would like.
Concrete Cube Sample Breaking Test Standards
Standards for different concrete testing methods are either set by global standards or by the customer.
All aspects and details needed to perform the tests should be outlined and ensured that they are done properly.
The standards for the concrete cube specimen strength test are as follows:
Fresh Concrete:
EN 12350-1:2019 – Sampling
EN 12350-2:2019 – Fresh Concrete Test, Slump Test
EN 206:2013+A1:2016 – Concrete. Specification, performance, production and conformity
Hardened Concrete:
EN 12390-1:2012 – Shape, dimensions and other requirements for samples and molds
EN 12390-2:2019 – Preparation and Curing of Samples for Strength Testing
EN 12390-3:2019 – Compressive Strength of Test Samples
EN 12390-4:2019 – Compressive Strength – Specification of Testing Machines
Concrete Cube Sample Strength Test Formula
As for testing the compressive strength of any material, the formula is:
Compressive Strength = Load / Section Area
Concrete Cube Sample Compressive Strength Testing Procedure
Concrete Cube Sample Breaking Test
Performing a test for the compressive strength of a concrete cube consists of several steps.
First, the tested concrete is poured into a mold that meets the above-mentioned size requirements - 150 x 150 x 150 mm.
Secondly, the concrete is properly bottled in order to remove the voids or air in the concrete.
Then, after curing for 24 hours, the test specimens are removed from the molds and placed in the curing pool to regulate the curing time.
After the samples are cured for the time specified in the project specifications, the surface of the samples is made smooth and smooth.
The sample is then placed in a compressive strength test press and load is applied gradually until the sample breaks.
