Self-consolidating concrete (SCC) is a highly flowable, yet stable concrete that can spread readily into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation and without undergoing any significant separation of material constituents. SCC has many advantages over conventional concrete, such as: eliminating the need for vibration; decreasing the construction time and labor cost; reducing noise pollution; improving the filling capacity of highly congested structural members; improving the interfacial transitional zone between cement paste and aggregate or reinforcement; decreasing the permeability and improving durability of concrete; and facilitating constructibility and ensuring good structural performance. SCC has been attracting more and more attention worldwide since its introduction in the late 1980s. New applications for SCC are being explored. To promote and encourage the use of SCC, ACI Committee 236, Material Science of Concrete, and ACI Committee 237, Self-Consolidating Concrete, organized two technical sessions on “Workability of SCC: Roles of Its Constituents and Measurement Techniques” at the ACI Spring 2005 Convention in New York City, New York. Eleven papers were presented covering a wide range of practical case studies and research projects on the design, testing, placement, and performance of SCC. This Special Publication (SP) contains 10 of the papers presented at the sessions. Six of the papers deal with the mixture proportions and the effects of raw materials on workability; two of them deal with the rheometer testing of SCC; one deals with form pressure; and one deals with the structural response of SCC frames under earthquake loading. On behalf of ACI Committees 236 and 237, the editors would like to thank the authors and presenters for their contributions to the technical sessions and this volume, the reviewers of the original manuscripts for their constructive comments and suggestions, and the ACI staff for their help in organizing the sessions and preparing this SP. It is our hope that the success of these technical sessions and the publication of this SP will encourage and facilitate the use of SCC.
