HIGHLY DURABLE CONCRETE USING DURABILITY IMPROVING AGENTS FOR LONG TIME USE OF STRUCTURES

Kunio Yanagibashi; Yasuhiko Yoshioka; Toshio Saito

Durability improvement of structural materials is essential for extending the service life of structures. Reinforced concrete construction, which is the most common, is composed of concrete and internal steel reinforcement. Since concrete also serves to protect internal steel against corrosion, long-life structures may be obtained by improving the corrosion-protective capability of concrete. The authors used a mixture of glycol ether derivatives and amino alcohol derivatives as a durability improving agent and evaluated its effects. The effects of using silica fume with the durability improving agent were evaluated as well. The results indicated that concrete containing the durability improving agent and silica fume is promising as a material for high durability reinforced concrete.
