INTRODUCTION TO DOCOMOMO INTERNATIONAL SPECIALIST COMMITTEE ON TECHNOLOGY (ISC-T)
Kyle Normandin
This is the first of four sessions focused on the theme of concrete research and methodologies. Organized as a collaboration of Docomomo US and the Docomomo International Specialist Committee on Technology, this two-day Docomomo ISC-T seminar is the first to be held in the United States in more than ten years. The mission of the (ISC-T) is to promote documentation and conservation through studies of, and research into, technology, and into the material qualities of modern architecture. The committee organizes seminars; it also supports and participates in workshops related to the technology of modern buildings.
SCHOKBETON HISTORY - ZWIJNDRECHT
Lucas van Zuijlen
In the 1930s the need for cheap building materials became a worldwide economic crisis and for concrete, cement was the most expensive component. A method to fabricate more dense concrete of the same strength using less cement and water was desired and shaking/shocking was developed to facilitate the reduction. Zwigndrecht concrete-work G. Lieve soon found out that shocked concrete was much stronger than regular concrete. In 1932 the Schokbeton firm was created and rapidly expanded into a worldwide company. The presentation introduces the patented shock technique consisting of the idea that at the start of the hardening process, the liquid material will compact.
SCHOKBETON PRECAST SYSTEM / ARCHITECTURAL PRECAST CONCRETE TECHNOLOGY STEERING DESIGN

The presentation introduces the lay preservationists and preservation professionals to the basic characteristics of concrete and precasting followed by a focused survey of the early development of architectural precasting and its evolution in the 20th century. This evolution will be set in the context of competing precasting technologies and will finally focus on Schokbeton, its significant qualities and its impact on design and construction of important 20th century buildings across the globe.
