Special Concretes Workability and Mixing, P.J.M.Bartos




Preface

Special concretes are a fast growing area of concrete technology where a stage

has been reached in which the practical construction industry has to adjust its site

practice in order to maintain efficiency and high quality of its products while

using a wide range of mixes very different from the traditional ones.



This book consists of papers presented at the International Workshop on

Special Concretes: Workability and Mixing. The Workshop was held under the

auspices of the International Union of Testing and Research Laboratories for

Materials and Structures (RILEM) at the University of Paisley in Paisley,

Scotland, on 1–3 March 1993.



The Workshop marked the end of the first year of activity of the RILEM

Technical Committee 145-WSM on Workability of Special Concrete Mixes in

which it concentrated on the survey of the current knowledge and information.

The Workshop brought together invited experts in the field of special concrete

who all took an active part in presentation of papers, practical test

demonstrations, and an extensive discussion in a true workshop format. The focus

of the Workshop was on practical aspects and most of the participants were from

industry and had a direct experience with the production or applications of the

special concretes. An appropriate fundamental scientific support was also

provided by the industrial and academic researchers present at the Workshop.



The organization of this event was a dedicated team effort. The technical

programme and the selection of the contributions, followed by the chairmanships

of the sessions were carried out by the members of the TC 145-WSM and I wish

to thank particularly Dr David Cleland (Belfast), Dr S. Karl (Darmstadt), Dr

Claude Legrand (Toulouse) and Mr Örjan Petersson (Stockholm) who devoted

much of their personal time and energy and helped to organize the Workshop at

very short notice. The cooperation with TC 150-ECM through its Chairman,

Professor H.Beitzel (Trier), enabled the mixing process to be included in the

theme of the Workshop and made it even more relevant to the needs of practical

construction.


Without a principal commercial sponsor, the event relied financially on the

goodwill of the University of Paisley which kindly agreed to underwrite the costs

of the Workshop. This and the support of the many individual small sponsors

who made the event financially viable are gratefully acknowledged.
