High-Strength Concrete for Wall foundation using Ternary Blended Cement with Intermixture of Blast-Furnace Slag and Fly Ash

Abstract

The anchorage of the Akashi, Kaikyo bridge in Japan, the world's longest suspension bridge, will be constructed as a concrete foundation surrounded with underground wall of depth of 75 m. This wall is composed of 46 slender reinforced concrete panels. A high strength, low-heat generating concrete using a ternary blended cement containing large amounts of blast furnace slag and fly ash, and superplasticizer were used. This paper describes the results of tests on basic properties such as workability, strength, heat generation of high strength concrete using ternary blended cement with large amount of blast furnace slag and fly ash, the results of tests performed on experimental models, and the results of actual work.
