A Rockwell Hardness Test for Concrete

CODEN: CCAGDP

Abstract

The standard superficial Rockwell 15Y hardness test has been adapted for use on concrete. Hardness measurements were made on the mortar regions between the coarse aggregate pieces. A correlation between this hardness and the concrete's compressive strength was developed. For 7.5- by 15-cm (3- by 6-in.) cylinders, it is Rockwell 15Y hardness = 73.5 (log compressive strength in psi) — 187 or 73.5 (log compressive strength in MPa) — 28.0. Various effects of specimen preparation and size are discussed, as are the statistics of the test.
