INVESTIGATION OF PORTLAND BLAST-FURNACE SLAG CEMENTS

THIS REPORT DISCUSSES THE FOLLOWING STUDIES MADE TO SUPPLEMENT THE FIRST REPORT OF THIS SERIES: A STUDY OF EFFECTS OF ABBREVIATED MOIST-CURING OF CONCRETE REVEALED NO INDICATIONS THAT CONCRETE CONTAINING PORTLAND BLAST-FURNACE SLAG CEMENTS IS MORE ADVERSELY AFFECTED THAN TYPE II CEMENT CONCRETE. TESTS OF EFFECTS OF PORTLAND BLAST-FURNACE SLAG CEMENT ON CORROSION OF REINFORCING STEEL SHOWED THAT CORROSION AT ALL AGES AND EXPOSURES TESTED WAS SIGNIFICANTLY LESS FOR STEEL IN THIS CONCRETE THAN FOR STEEL IN TYPE II PORTLAND CEMENT CONCRETE. BOND-TO-STEEL TESTS INDICATED SIMILAR RELATIONS FOR BOTH BLAST-FURNACE SLAG AND TYPE II PORTLAND CEMENTS. EXPOSURE OF 108 CONCRETE SPECIMENS MADE WITH PORTLAND BLAST-FURNACE SLAG CEMENT, BLENDS OF THIS AND A NATURAL CEMENT, AND WITH TYPE II PORTLAND CEMENT TO 7 YEARS NATURAL WEATHERING REDUCED THE MODULI OF ELASTICITY BELOW THE INITIAL VALUE IN ONLY FIVE SPECIMENS, ALL BLENDS WITH NATURAL CEMENT. SUMMARIES OF INVESTIGATIONS OF PORTLAND BLAST-FURNACE SLAG CEMENTS MADE FOR ACTUAL CONSTRUCTION PROJECTS ARE INCLUDED AS APPENDIXES A AND B. /AUTHOR/
