THE MICHIGAN STATE HIGHWAY DEPARTMENT HAS NOT SO FAR EXPERIENCED DISTRESS OF FIELD CONCRETE POSITIVELY IDENTIFIED AS BEING DUE TO CEMENT ALKALI-CARBONATE ROCK REACTION. HOWEVER, LABORATORY STUDIES HAVE FOUND THREE QUARRIED LIMESTONES HAVING VERY MILD EXPANSIONS WHEN INCORPORATED IN CONCRETE MADE WITH ALKALI CEMENT. NINETEEN OTHER LIMESTONES AND SEVENTEEN NATURAL GRAVELS SIMILARLY STUDIED SHOW NEGLIGIBLE EXPANSIONS. EXPANSION DATA UP TO 4 YEARS AGE ARE PRESENTED FOR SEVERAL OF THE AGGREGATES STUDIED. TWO OF THE LIMESTONES WHICH ARE MILDLY REACTIVE EXHIBIT DEPENDENCE OF FREEZE-THAW DURABILITY ON THE ALKALI CONTENT OF THE CEMENT WHEN THE AGGREGATES ARE PLACED IN THE CONCRETE IN A VACUUM SATURATED CONDITION. DURABILITY IS IMPROVED WITH LOW ALKALI CEMENT. THE THIRD MILDLY REACTIVE LIMESTONE HAS NOT BEEN SIMILARLY STUDIED BECAUSE ITS FREEZE-THAW DURABILITY EVEN WITH HIGH ALKALI CEMENT IS GOOD, AND IT IS DOUBTFUL THAT IMPROVEMENT IN DURABILITY WITH LOW ALKALI CEMENT, IF PRESENT , COULD BE RELIABLY MEASURED. DEFICIENCIES IN THE COMPLETENESS OF THE PRESENT DATA EXIST BECAUSE ONLY PORTIONS WERE PRODUCED ON A PLANNED RESEARCH BASIS. THE REMAINDER WAS OBTAINED AS A MINOR SUPPLEMENT TO ROUTINE ACCEPTANCE TESTING . /AUTHOR/
