Abstract:
Traces the evolution of high-strength concrete in the Washington, D.C. area as experienced by a ready-mixed concrete producer. The proportioning process and the use of local materials are reviewed. As strength requirements increased, the experience gained from each preceding mix was used in formulating the higher strength mixes. Improved field and laboratory testing techniques are recommended.
