Design of Low Carbon Footprint Alkali Activated Slag Cement Concretes for Marine Engineering Application in China

Abstract

The paper covers the results of studies of the alkali activated slag cement concretes from the cements prepared under all-in-one technology to meet the requirements for concretes for marine engineering application. The compressive strength, weather resistance, biodegradability, bonding strength with steel reinforcement bar, steel reinforcement bar protection, chlorine ions diffusion parameters and resistance to corrosive exposure of 5% Na2SO4 solution were tested, which exhibit that alkali activated slag cement and concretes are very suitable for marine engineering applications.
