...Jing-Han Liu; Xiao-Bao Zuo; Yu Zhang The phase conversion of metastable products in calcium aluminate cement ( CAC ) at elevated temperatures can significantly affect its durability. This study systematically investigates the degradation and leaching behaviour of CAC-based materials in water...

..., the specific impacts of cement-stabilized soil on the pH and hardness of groundwater remain poorly understood. In this study, cylindrical leaching experiments were employed to elucidate the alterations in pH and hardness of leachate derived from cement-stabilized soil under various conditions. The findings...

...Shaowei Wang; Wenlong Gao; Yanyu Xiao; Jiawen Wu; Qun Xia Chloride penetration is one of the main causes of failure of reinforced concrete structures, especially in undersea tunnels, which is also accompanied by stress and seepage-induced calcium leaching. The chloride penetration resistance...

.... influencing the retention behaviour of radionuclides in engineered and natural barriers) due to water ingress. In the geochemical conditions in northern Germany, the porewater is of very high salinity, with salt contents of up to 2·5 M. In this work, the elemental composition of leaching water (with different...

...Napoleana Anna Chaliasou; Andrew Heath; Kevin Paine; Juliana Calabria Holley Despite extensive research into sustainability of geopolymers, end-of-life aspects have been largely overlooked. A recycling scenario is examined in this study. This requires an investigation of alkali leaching potential...

... called X-ray computed micro-tomography (micro-CT). To investigate this deterioration, an accelerated static immersion based leaching test with periodic abrasive action was performed on cement paste specimens of size 10 × 10 × 60 mm, prepared using ordinary Portland cement with a water-to-cement ratio...
