Properties of Concrete with Portland Blast-furnace Slag Cement Type A Consisting of a Blend of Ordinary Portland Cement and Blast-furnace Slag Cement Type B

Abstract

Research on ecological concrete has focused mainly on concretes that use cement equivalent to type C blended cement that enormously reduce carbon dioxide emissions. However, such concretes often presents restrictions in terms of production, construction and application locations, which makes them difficult to use for general purposes. This paper describes an investigation of concrete that uses cement equivalent to blast furnace cement type A consisting of a blend of ordinary portland cement and blast furnace cement type B and was found to produce desirable characteristics in terms of fresh concrete properties, strength development, durability, and carbon dioxide reduction effect.
