Cube Testing has, over the years, become theroutine standard test for checking that concrete conforms to design specification. Traditionally,Cube Moulds have been constructed from steel and cast iron and are manufactured to extremely tight engineering tolerances. Ofthese tolerances the most important has been shown to be that for flatness of the sides. Some years ago a research project was carried out to compare results obtained with the same concrete mix using some Cube Moulds with flatness's inside the old BS tolerance for new Moulds of 0.03mm (the best) and some approaching the maximum in use tolerance of 0.06mm (poorer). Results showed that samples made from the same batch of Concrete in thebest Moulds were giving noticeably better results in compression tests than the poorer Cube Moulds This difference in results is because on samples made in the best Moulds, the compression load is spread uniformly across the two parallel faces of the sample, but samples made in the poorer Moulds which have imperfect faces (possibly convex or concave), the compression forces are applied unevenly to only parts of the faces. Cube strengths are adjusted by changes to the concrete mix design; to make the concrete stronger usually more cement (the most expensive component of the mix) is added. Therefore, a company using top quality AEP Products India Pvt. Ltd. Cube Moulds will need to use less cement in their concrete to achieve test results inside specification than another company who are using poor quality Cube Moulds. The cost of this additional cement will be significantly more over time than the
