Summary: | 碩士 === 國立中興大學 === 土木工程學系 === 89 === This study investigates the mechanical properties of medium strength high performance concrete (TAICON). Experiments focus on the strength development , the stress-strain behavior in uniaxial compression , the modulus of elasticity , and the Poisson’s ratio.
The test results show that by adding pozzolanic material the workability of TAICON can be improve , the compressive strength at later ages is increase . Also , the compressive strength can reach to over 40MPa , but the modulus of elasticity are lower than that of prediction value.
When replacing parts of cement by pozzolanic material , the more replacement percentages of slag will result in less amount of required sp and larger compressive strength and the modulus of elasticity . Current prediction models of ACI 318 and ACI 363 are found to be overestimated the modulus of elasticity of TAICON .
