THE SODIUM SULFATE TEST DESCRIBED IN THE U.S. DEPARTMENT OF AGRICULTURE BULLETIN IS DISCUSSED. AGGREGATES WHICH FAIL THIS TEST ARE USUALLY SOUND AND DURABLE AND SOME OF THESE AGGREGATES MAY MAKE CONCRETE OF SATISFACTORY DURABILITY. SEVERAL LABORATORIES ARE USING THE REPEATED FREEZING AND THAWING TESTS IN PREFERENCE TO THE SOUNDNESS TESTS. OTHER TYPES OF ACCELERATED TESTS FOR AGGREGATES ARE BEING STUDIED. AT PRESENT, THE ALTERNATE FREEZING AND THAWING TEST APPEARS TO BE THE BEST FOR DETERMINING THE DURABILITY OF CONCRETE TO WEATHERING. ATTENTION IS CALLED TO THE RAPID GROWTH IN THE USE OF THE CROSS-BENDING TEST AS A METHOD OF FIELD CONTROL OVER THE TRANSVERSE STRENGTH OF CONCRETE FOR ROAD CONSTRUCTION. THE DESIRABILITY OF ASCERTAINING THE EFFECT OF SHAPE AND SURFACE CONDITION OF THE CONSTITUENT AGGREGATE PARTICLES ON THE STRENGTH OF CONCRETE SEEMS TO BE A VERY IMPORTANT PROBLEM.
