Experimental Study on the Characteristics of GGBS Concrete Bending Specimens

Abstract:

This paper reports the experimental study on the mechanical characteristics of bending component with ground granulated blastfurnace slag (ggbs). A laboratory study has carried out to investigate the influence of replacement ratio of GGBS on the mechanics and deformation of concrete bending specimen; the harmonious working of concrete and reinforced bar is discussed as well. The results indicate that although the proportion of slag improve the strength of the concrete, the mechanical performance of GGBS concrete bending specimen is quite similar to that of common concrete, and the design expressions of common concrete girder is available to GGBS concrete girder. The specimen experiment also proves the existance of optimum slag proportion in GGBS concrete specimen, and the girder performs well when replace 20% cement with slag.
