Despite the excellent properties and performance of precast concrete products, their usage has not appreciably increased with respect to cement usage. Even a decreasing trend has been recognized recently. However, utilization of precast concrete products is essential in view of the foreseeable changes in the social circumstances. The Committee has therefore conducted research and investigation to confirm the problems and the facts that the precast products have been facing and formulate technical materials that will contribute to their wide-spread use and development. This research revealed differences in the attitudes toward precast products between designer, constructor and precast manufacturers, problems related to the transition to performance-oriented design, and subjects to be addressed when using low quality materials, including recycled aggregate, for precast products.
