原始语种摘要: This paper investigates the effectiveness of NaOH concentration and fly ash dosage on the mechanical properties, pore structure, water resistance, and water permeability of a new mortar manufactured by using a special kind of sandstone and fly ash. Mechanical properties were evaluated by means of compressive strength. Mercury intrusion porosimetry (MIP) was employed to investigate the pore structure and pore size distribution. A water permeability test was carried out to find out the permeation characteristics of Pisha sandstone-based mortar. Thermogravity and differential scanning calorimetry (TG-DSC), Fourier transform infrared (FTIR) analysis, and scanning electron microscopy (SEM) were used to analyze the reaction products, indentify the phases of the reaction products, and observe...
