...Yan Wu; Yi Zhang; Jiayi Qiu; Yefei Li; Sihong Xia pH and hardness are crucial physicochemical properties of groundwater, exerting a substantial influence on the formation of underground ecosystems. The application of cement-stabilized soil has the potential to modify these characteristics. However...

... and natural tests, the temperature was 23°C and the relative humidity was 55%. Concrete pH profiles were obtained by combining the water extraction method (Haque and Kayyali, 1995) and the pore solution extraction method (Barneyback and Diamond, 1981). For the water extraction method, concrete powder...

...Mengtian Li; Xiao Zhang; Bin Han; Dong Tian In this study, the effect of pH value, a neglected but important factor of magnesium phosphate cement (MPC) pastes, was investigated to generate new ideas in the field of large water-to-solid (w/s) fraction MPC preparation. To avoid the introduction...

...) was enabled by way of the adjustment of curing conditions. The influence of IAH and SBC on hydration kinetics was evaluated by isothermal calorimetry, hydration degree and pH measurements. Mechanical performance results were supported by X-ray diffraction, thermogravimetric analysis and scanning electron...
