Describes investigations leading to preparation earlv in 1935 of one of the first (if not the first) consumer specifications for purchase of sulfate resisting cement. Cements of a wide range of compositions were tested. From evidence of their relative resistance to corrosion in sodium sulfate solutions, it appeared that a cement having a composition with maximum limits of 4 percent for C3A, I2 percent for C3A plus C4AF, and 50 percent for C3S would be hiqhly sulfate resistant. Subsequent tests have proved cement manufactured under such specification to be much more resistant to sulfate corrosion than cements of other composition.
