Resumen
In this research, the most important properties of HPC were analyzed. The study was focused on HPC with specified28 days compressive cylindrical strengths between 60 to 110 MPa and made with locally available materials: RapidHardening Portland Blast Furnace Slag Cement, siliceous aggregates and commercial admixtures. Compressive andflexural strength, elastic modulus, abrassion resistance and shrinkage properties were analyzed and modeled usinginnovative methods. Laboratory test results showed that it is possible to develop a general model for compressive strengthcombining a hyperbolic equation for strength evolution and an exponential equation for mix design parameters. It was alsoconcluded that the measured moduli of elasticity are lower than the predicted values by ACI 363 and ACI 318 equations,and that the square root of the compressive strength did not turn out to be a good predictor of the flexural strength, for theused materials. Furthermore, it was concluded that the ASTM C944-99 abrassion test is not very effective to measureabrassion resistance of HPC, due to the high variability of results. Strain measurements showed that autogenous shrinkageis a significant part of the total shrinkage. It was shown that the FIB 2000 model is adequate to predict shrinkage of HPC,but some coefficients must be updated to local conditions. An updating method for shrinkage models was successfullyapplied
