This paper investigates the effect of graphene on the properties of slag and fly ash-based ambient cured geopolymer paste and mortar. Graphene was added with five percentage (0.0%, 0.1%, 0.5%, 1.0% and 1.5%) of aluminosilicate materials by weight. The initial and final setting times of geopolymer pastes were reduced. The workability of geopolymer paste and mortar was slightly decreased with graphene. The 7-day and 28-day compressive strength of geopolymer mortar with 1.0% addition of graphene in...

Abstract The use of seawater and sea-sand in producing concrete has attracted increasing research attention in recent years to address the shortage of river sand and in certain applications the shortage of freshwater. In particular, reinforced concrete structures made of seawater sea-sand concrete (SSC) and corrosion-resistant fiber-reinforced polymer (FRP) are particularly attractive for the development of coastal and marine infrastructure (e.g. on remote islands) as durable structures can be ...

The following research projects will receive funding from the ACI Foundation: Standard Critical Chloride Threshold Test Variability due to Material Sources: principal investigator Ceki Halmen, University of Missouri - Kansas City. Endorsed by ACI Technical Committee: 222 Corrosion of Metals in Concrete.  The large variability of published CT data and lack of a standard CT test method creates significant difficulties for the concrete industry. Researchers cannot compare CT values obtaine...

Abstract In this paper, the mechanical properties of magnesium phosphate cement (MPC) was enhanced by adding fiber and nano-Al O . The effects of fiber and nano-Al O on the workability, compressive strength and flexural toughness of MPC were studied. The variables of the experimental investigation included the types of fiber, fiber volume fraction, nano-Al2O3 substitution rate and curing time. The experimental results showed that the workability and the mechanical properties of the MPC could b...
