STUDY TO REFINE METHODS AND PROCEDURES FOR IMPLEMENTING THE METHOD OF EARLY PREDICTION OF POTENTIAL STRENGTH OF PORTLAND CEMENT CONCRETE
The study is based on two designed experiments to further increase the practicality of using early (+ or - 24 hour) tests of concrete test cylinders made at the job-site as a means of quality control of concrete. The scope of the work included concrete of four cement constants, so proportioned as to simulate field conditions where part of the cement was inadvertently omitted. Also the effect of two retarding admixtures on the early strengths of concrete of normal cement concrete was investigated. Specimen cylinders were tested at from one to three days of age without pretreatment, and with the use of both celotex pressure pads and sulphur mortar caps.
