WebJan 1, 1992 · It is my understanding that the concrete member design equations (beams, columns, etc) are done in BS EN 1992-1-1 using the characteristic strength that is based on cylinders. Hence, say the characteristic strength would be 30 MPa, then the concrete would be given Grade 30/37. WebConcrete cylinder and cube specimens for compression testing were compared through a survey of past research, including testing procedures, factors affecting the cylinder/cube strength ratio, and conversion factors and equations. The main difference between cylinder and cube testing procedures is capping. Cylinder ends are usually not plane or ...
