Abstract ：
Herein, the effects of the ionic types and content of alkali activator on the chloride-ion permeability of one-part alkali-activated nickel slag concrete were examined. The NT Build 492 method was adopted to measure the Cl- transport performance. In general, the total Cl- concentration in concrete decreases with the increase of penetration depth; however, the enrichment of Clconcentration in the sample is not obvious. Anions have more effect on 28-d compressive strength, while cations have more effect on chlorine-ion permeability. For the same Na2O content, SiO32- -activator and Na+-activator perform better than other anions and cations, while OH- and K+ perform worse than other ions. The chloride-ion permeability coefficient (DRCM) of concrete with Na2SiO3 is the lowest and that with KOH is the highest. The DRCM of concrete prepared with KOH is 1.93 times higher than that of concrete prepared with Na2SiO3. When the activator is Na2SiO3, the DRCM of concrete decreases with the increase in Na2O content when the Na2O content is less than 7%. However, when the Na2O content exceeds 7%, the DRCM of concrete increases with the increase in Na2O content.

Abstract ：
To address the significant carbon emissions caused by the cement industry and its contribution to the greenhouse effect, there is an urgent need for new construction materials that can substantially reduce the use of traditional Portland cement. Alkali-activated binders, known for their excellent performance and lower carbon footprint, have emerged as a promising alternative. Despite the numerous advantages of geopolymers, their practical application is hindered by challenges in processability required for construction techniques, such as pumping, spreading, and forming. This study focuses on enhancing the rheological properties of geopolymers through mechanochemical activation and exploring the modification mechanisms involved. Slag and fly ash raw materials were processed under different ball milling conditions, specifically varying ball milling rotation speed (BR) and ball milling time (BT). The mechanical properties, workability, and rheological behavior of geopolymer specimens were evaluated to identify the optimal milling parameters affecting these properties. Detailed analysis using XRD, SEM, and heat of hydration tests elucidated the phase composition, microstructural evolution, and thermal characteristics of mechanochemically modified geopolymers, providing insights into the fundamental mechanisms of mechanochemical activation modification. The results indicate a significant correlation between ball milling parameters and the rheological properties of geopolymers. The optimal milling regime was identified as grinding at a speed of 70r/min for 50 min. This specific milling condition imparts ideal properties to the geopolymer, including moderate yield stress (34.353 Pa), low plastic viscosity (0.452 Pa s), good thixotropy, and high 28d strength (53.28 MPa), without any significant shear thickening behavior. © 2024

Abstract ：
Carbonation leads to the decrease of alkalinity of concrete, which seriously harms the durability of reinforced concrete structures. In this paper, Na2 SiO3 , NaOH and Na2 CO3 were used as alkali activators, and the influences of the types of alkali activators and Na2 O equivalent on the carbonation resistance of single-component alkali-activated nickel slag cement mortar were investigated. The results show that, when the Na2 O equivalent is the same, the carbonation resistance of single-component alkali-activated nickel slag cement mortar is the best in the single doping of NaOH samples, and the carbonation resistance is the worst in the single doping of Na2 SiO3 samples. Na2 CO3 partial substitution for Na2 SiO3 can improve the carbonation resistance of cement mortar samples, while the effect of Na2 CO3 partial substitution for NaOH on the carbonation resistance of cement mortar specimens is related to the Na2 O equivalent. With the increase of Na2 O equivalent, the carbonation resistance of single doping of Na2 SiO3 and mixed doping of Na2 SiO3 &Na2 CO3 (3 ∶ 1) samples increases first and then decreases. The carbonation resistance of single doping of NaOH samples increases continuously in the early stage, and increases first and then decreases in the later stage. The carbonation resistance of mixed with NaOH&Na2 CO3 (3 ∶ 1) samples improves in the early stage, but decreases in the later stage. © 2023 Bulletin of the Chinese Ceramic Society.
