The effect of fine sand of blast-furnace slag (SBFS) on freeze-thaw resistance, sulfate resistance, and sulfuric acid resistance in mortar whose aggregate is replaced in part or in full with blast furnace slag (SBFS) was investigated. Evaluation carried out on small test specimens confirmed that freeze-thaw resistance, sulfate resistance, and sulfuric acid resistance all improve as the SBFS substitution rate increases. However, increased porosity with a larger proportion of pores sized 50 nm or larger was also observed. In the case of the use of molten slag from municipal solid waste (SMSW), no improvement in freeze-thaw resistance was observed with increases in SBFS substitution rate.
