ABSTRACT:
A method and apparatus for supporting concrete testing samples comprising providing closely machined aluminum, steel, or suitable molded plastic caps for the respective circular ends of a cylindrical concrete testing sample and removable, reusable flanged molded elastomeric pads which are inserted in a recessed cavity in each cap prior to positioning of the cap on the respective end of the concrete cylinder. Each pad has a space between the bottom and the side to provide at least an equivalency between sulfur capped cylinder compression load strengths and those generated by the above system over the wide range of compression load values normally occurring in this particular test.
