Abstract:
Traditionally, the compressive strength of concrete has been determined using 6 x 12 in. (152 x 305 mm) concrete cylinders. This article discusses the development and use of 4 x 8 in. (102 x 203 mm) concrete cylinders for quality control of concrete. The testing program employed is outlined and the test results and their significance are also discussed. Advantages and disadvantages of using the smaller cylinders are pointed out and it is concluded that the 4 x 8 in. cylinder can be successfully used for accep-tance testing.
