According to the test, An increase of super-retarding-agent (SRA), which combined the SRA with admixture, delayed initial and final setting time. Interestingly control concrete incorporating only admixture also retarded setting time. In addition concrete, adding combination of the SRA and admixture simultaneously, exhibited considerable results, due to the absorbing, pozzolanic and potential hydraulicity reaction of the admixture. Overall, to secure initial setting time as control concrete does, particular coefficient value considering the properties of each materials, should be applied, before it is placed in the field construction.
