EVALUATION OF CYLINDER SIZE AND CAPPING METHOD IN

Sulfur caps were compared with unbonded polymer pads in compressive strength testing of concrete within the strength range 3000 to 18 000 psi (20.7 to 124.2 MPa). A less extensive study, still in progress, compares polymer pads with ground surfaces and lapped surfaces within the range of 13 000 to nearly 20 000 psi (89.7 to 138.0 MPa). Test cylinder size, 6 by 12 in. (152 by 305 mm) and 4 by 8

specimens, particularly 4 by 8-in. cylinders, for concrete compressive strength tests. With smaller cylinders a person can handle them easier, spend less time and effort preparing them, and use less material. However, there is a debate over the strengths of the 4 by 8-in. cylinders compared to 6 by 12-in. cylinders.
