15

The correct answer indicates that the molding of strength test specimens should commence within 15 minutes after the composite sample is fabricated. This time frame is crucial because the workability and characteristics of freshly mixed concrete can change rapidly. If the specimens are not molded within this specified period, the concrete may begin to set, which can adversely affect the accuracy of the strength tests. This time limit helps ensure that the specimens reflect the properties of the concrete as intended for testing, thus guaranteeing the reliability and validity of the strength test results. Adhering to this timeframe is fundamental in achieving consistent and comparable test outcomes in concrete quality control.
