Effect of Ground Quartz Sand and Ground Granulated Blast-Furnace Slag on Properties of High-Strength Concrete in the Steam and Autoclaved Curing

Abstract:

High-strength concrete in the autoclaved-curing was made by the way of mixing single and double doped. The compressive strength of concrete and the morphology of hydrates in concrete containing ground granulated blast-furnace slag (SG) and Quartz sand (QS) have been investigated using XRD and SEM measurements. The results show that quartz sand also possesses effective pozzolanic property in the steam-autoclaved stage. The mixed proportion of QP:SG=1:1 is the best when the dose is 30%.The paste became denser through double mixing. When the doses is 10-35%, SG for the improvement of concrete compressive strength is higher than the quartz sand.
