The modified Fenton paper sludge ash (MFPSA) was employed to replace cement in different proportions to prepare fiber cement products. The mechanical and hydrophobic properties of the MFPSA/fiber cement and concrete were studied. When the calcination temperature is 800 degrees C and the dosage is 4%, the MFPSA increases 28d flexural strength of fiber cement by 11.5%, compressive strength by 5.7%, and decreases water absorption by 2.6%. The MFPSA also decreases the 28d capillary water absorption of fiber concrete by 31.9%. The XRD, SEM/EDS, FTIR were employed to reveal how the MFPSA affects the...
