The results showed that the lowest pouring temperature was 1081℃ when the co-melting ash and sludge were in the ratio of 7:3. The molten slag was then water-cooled and examined its properties. It was observed that the water-quenched slag was amorphous and had a specific gravity of 3.15 which was close to Class C fly ash. The results of compressive strength, degree of hydration, MIP and SEM indicated that the slag was a latent pozzolans and it could replace 3% to 20% cement in mortar. It was also observed that 3% replacement of cement with slag would enhance concrete properties with denser microstructure based on resisitivity and RCPT results.application/pdf240045 bytesapplication/pdfzh-TW國立臺灣大學環境工程學研究所熔融卜作嵐性質電阻係 數快速氯離子滲透耐久性meltingadmixturespozzolanic reactiondurabilityFriedel’s salts[SDGs]SDG11[SDGs]SDG12reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/22159/1/932211E002036.pdf
