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 .
