STRENGTH TESTS AT EARLY AGES AND AT HIGH SETTING TEMPERATURES

In some tropical countries, because of the favorable labor and weather conditions, concreting is frequently carried out 24 hours a day. This continual and high rate of placing of concrete requires a rapid control method for the estimation of potential strength. This paper presents a rapid control method by which compressive strength test results of concrete cubes 24 to 48 hours old will closely predict strengths at later ages. Test results of the cubes in which the setting temperatures are 113, 122, 131, 140, and 149 F (45, 50, 55, 60, and 65 C) are also presented. These setting temperatures considerably reduce the potential concrete strength. This reduction in strength is found to increase as the water-cement ratio and setting temperature increase.
