High-performance concrete (HPC) is concrete meeting special combinations of performance and uniformity requirements that cannot always be achieved routinely using conventional constituents and normal mixing, placing, and curing practices. Nowadays, with the development of construction, the higher buildings do not demand only the greater amount of concrete also demand the higher concrete strength. In addition the decrease of carbon dioxide discharged during the production of cement is an important issue, because carbon dioxide is a naturally occurring greenhouse gas. The replacement of fly ash in concrete thereby not only produces a very high strength or performance concrete but also reduces the production of cement using in construction industry leading to a decrease in CO2. Most prediction models are greatly dependent on the aggregate properties and mix proportion, including CCL2001 model, which is a prediction model for the local material in Taiwan. Simultaneous with the increasingly popular of high-performance concrete containing fly ash, the CCL model needs to be modified to predict exactly for HPC using fly ash. The result of analysis indicates that a modified CCL model is more suitable for prediction of shrinkage and creep in HPC using fly ash than the original model.
