Self consolidating concrete for precast prestressed concrete bridge elements

It uses descriptions and case studies throughout, as examples of specific types of applications, to identify where the practitioner needs to focus attention.

This book bridges the gap between research and practice.

Because of the variety of materials employed in the United States in the precast industry (cement type, supplementary cementitious materials, and specialty admixtures), there is a need to better understand the influence of these materials combinations on the properties of fresh and hardened concrete used in prestressed concrete construction and to identify reliable test methods and performance specification for mix design and quality control of SCC.

This report presents recommended guidelines for the use of self-consolidating concrete (SCC) in precast, prestressed concrete bridge elements.

These guidelines address the selection of constituent materials, proportioning of concrete mixtures, testing methods, fresh and hardened concrete properties, production and quality control issues, and other aspects of SCC.

Each necessary step is thoroughly dealt with and explained in a nice and pedagogic way." —Peter Billberg, Swedish Cement and Concrete Research Institute (CBI) "Quite comprehensive and with a narrative style at the practitioner level." —Lloyd Keller, Director of R&D and Quality Assurance, Ellis Don, Canada Self-consolidating concrete (SCC) is an innovative material used successfully throughout the world.

It is a highly flowable, non-segregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation, improving the overall efficiency of a concrete construction project.

SCC mixtures are highly fluid, yet their flowing properties can be adapted for a range of applications and allow practitioners to select and determine levels of filling ability, passing ability, and stability.
