The other important feature is the power and control unit which refers not only to International Standard
24/11/2019· In concrete compression test, normally 150mmx150mmx150mm concrete cube samples is used for testing. Why isn’t 100mmx100mmx100mm concrete cube samples used in the test instead of 150mmx150mmx150mm concrete cube samples?. Basically,the force supplied by a concrete compression machine is a definite value.For normal concrete strength application,say below 50MPa,

21/09/2017· Why do we weigh the weight of concrete cubes before crushing to a compression machine? I’d have said that we “record” the weight, or “determine” the weight. Or “mass”, even. But putting that aside, the reason is that we want to know reasons why th...
Cube Testing Machine is meant for testing the concrete cube which is part of a simple yet cost effective test process that allows in judging compressive strength of concrete as well as for quality assurance to ensure concrete is fit for defined purposes in line with defined industry standards.
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. Faulty manual
