Abstract:
At present, the design methodology and formula, particularly in shrinkage and creep, of Self-Compacting Concrete (SCC) projects in Taiwan are identical to those of Vibrated Concrete (VC), but there are differences in the composition and proportion of the materials in various regions, and obvious differences between the VC and SCC in engineering properties. In this study, the test data of shrinkage and creep in Taiwan and abroad were collected following the framework and parameters of the Northwestern University (NU) database to establish cloud-based analysis SCC database. Based on the Model B4-TW shrinkage and creep prediction model modified by Model B4, this study revised the characteristics of SCC and the localization to develop B4-TW-SCC. In B4-TW-SCC, the modification is mainly about the effect of high volume of cementing material weight and high sand ratio, as well as the effect of drying shrinkage changes on the drying creep. It is worth noting that efficiency in data mining and analysis of huge sets of data are significantly improved by analysis database in development of B4-TW-SCC. The creep curve and data point for specific SCC can be further generated on this cloud-based analysis database and directly implemented in common bridge design software for practical application.
