concrete testing solutions uk 25 years of industry experience. ctsl is a privately owned laboratory able to provide wholly independent professional and technical services to all concerned with the quality and performance of concrete and ground area. ctsl provides professional quality materials testing and consultancy services for uk,compressive strength of concrete and concrete testing,concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. in other words, we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. based on the test results, conformity can be checked as per the relevant standards.
testing of concrete. for all classes of concrete in production three cubes shall be tested at 7 days and three at 28 days or as required by the consultantclient. the average strength of the three cubes crushed at amp or 28 days shall be referred to as one test result. concrete shall be deemed to comply with the strength specified if,compression test on concrete civil engineering portal,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 indication of compressive strength of concrete. these are usually due to defects associated with testing machine.
mar 01, 2014 several studies have been conducted to investigate the potential of using crushed clay brick as an alternate aggregate. poon and chan investigated the possibility of using crushed clay brick as aggregates in sub-base materials. akhtaruzzaman and hasnat studied the use of crushed clay brick aggregate as a 100 replacement of coarse natural aggregate in concrete.,suitability of crushed manufactured sand,to determine the sample size of the test samples, it needs to consider the standards specifications. according to astm 33 it requires a minimum of 3 samples of cube size of 150 150 150 mm mold for each test of the characteristic compressive strength of concrete and 100 100 500 mm for flexural strength.
failure by crushing, and the failure load was recorded. the average failure load of the three specimens was then divided by the area of the specimens to obtain the compressive strength. in order to determine the density, the weight of each of the cube specimens at the point of testing for compressive strength was taken, and later,testing the compressive strength of concrete what,historical strength test records are used by the concrete producer to establish the target average strength of concrete mixtures for future work. how to test the strength of concrete. cylindrical specimens for acceptance testing should be 6 x 12 inch 150 x 300 mm size or 4 x 8 inch 100 x 200 mm when specified.
