Abstract
This study performed compressive, tensile and restrained shrinkage tests to find out the optimized mixture including shrinkage reducing admixture (SRA) and expansive admixture (EA) enabling to reduce the shrinkage of Ultra High Performance Fiber Reinforced Concrete (UHPFRC). The test results showed that the mixture using 1% of SRA and 7.5% of EA satisfied the design strength criterion despite of slight loss in the compressive and tensile strengths. In addition, this mixture exhibited the lowest restrained shrinkage strain by offsetting the quick setting and delaying the development of the restrained shrinkage stress.
