ABSTRACT
The performance of high-strength concrete is highly dependant on jobsite practices. Regardless of the strength or performance classification of the concrete, good materials, proportions, and production alone can never serve as a substitute for good jobsite practices. Even the most carefully designed high-strength concrete mixtures can perform poorly if good placement, consolidation, and, when necessary, finishing practices are not followed. Many problems that have occurred with high-strength concrete have been traced to poor jobsite control, particularly retempering practices and prolonged waiting times. Coordination and communication between all involved parties is essential for successful construction with high-strength concrete.
