Abstract: This paper is mainly to share the experience of SCC (self-consolidating concrete) that has been done in Taiwan. The main theme is to study the effects of aggregate packing types on the engineering properties of SCC. Three types of aggregate packing (primitive, dense and gap gradation) and five paste contents (1.2, 1.4, 1.6, 1.8, 2.0 of void within aggregate) are major parameters for evaluating the properties of SCC. The test result indicates the denser the aggregate packing the better the workability and engineering properties under sufficient paste content. The application of the densified mixture design algorithm (DMDA) to design SCC for every aggregate packing type can obtain high flowability and suitable strength growth. The strength efficiency of SCC designed by DMDA is much higher than that by traditional one. The significant contribution of the aggregate packing to the performance of hardened SCC is obvious.
