Nov 10, 2013· This limited experimental investigation examined the relationships between the compressive strengths of cubes, cylinders, cores and the estimated compressive strengths derived from pull-off tests for a relatively low-strength structural-grade concrete (
Keywords: cylinder/cube strength ratio, high-strength concrete, cylinder specimen, cubic specimen , As both types of specimen do not usually give the same strength, codes prescribe the use of a conversion factor between them This paper presents an experimental study, performed with eight types of high-strength concrete, showing that the .
In order to investigate if the Eurocode relationship between cylinder strength and cube strength also holds for local concrete, DEVB proposed to carry out a study in late 2012 The aim is to study the correlation between 150 mm dia by 300 mm cylinder strength and 100 mm cube strength ,
