Researchers and educators who specialize in the material science of concrete will find much to interest and challenge them in this Special Publication of the American Concrete Institute. It contains 35 papers presented at a symposium honoring Surendra P.Shah, Director Center for Advanced Cement-Based Materials, Northwestern University. Shah has made many contributions to our knowledge of concrete material science, fracture mechanics, high-performance concrete, and fiber-reinforced concrete ?all subjects that were covered at the symposium.

Topics for the presented papers include:

* Advances in fatigue and fracture
* Creep, shrinkage, and early-age cracking
* Laminated and fiber-reinforced cement composites

The last group of papers covers the future of research and education in concrete, with topics ranging from fracture mechanics applications for concrete to sustainable development for concrete. Thus SP-206 examines the past, present, and future of concrete material science.
