Freezing and Thawing Resistance of High-Strength Concrete.

摘要

The synthesis will be of interest to materials engineers, bridge designers, and others concerned with mixture proportioning, structural design, and construction of concrete bridges and highway appurtenances of high-strength concrete. Information is presented on the durability of high-strength portland cement concretes, particularly those made by using high-range water-reducing admixtures or silica fume. The synthesis explains the effects of high-range water-reducing admixtures and silica fume and makes recommendations with respect to the durability testing of high-strength concrete made with these products. The conclusions and recommendations are specifically applicable to highway bridge structural elements.
