CONCRETE AGGREGATES RESEARCH

THIS PAPER BRIEFLY OUTLINES THE OBJECTIVES OF A PROGRAM OF INVESTIGATION INTO CONCRETE AGGREGATES UNDERTAKEN BY THE NEW ZEALAND PORTLAND CEMENT ASSOCIATION. RESULTS OBTAINED SO FAR FOR TESTS ON MINERALOGICAL COMPOSITION, STRENGTH, PARTICLE SHAPE AND TEXTURE, DURABILITY AND DELETERIOUS SUBSTANCES ARE REVIEWED, TOGETHER WITH THE INFLUENCE OF AGGREGATES ON CONCRETE SHRINKAGE. SOME PRELIMINARY SUGGESTIONS ARE MADE CONCERNING THE LIMITATIONS OF SOME OF THE TESTS USED, THE NEED FOR ADDITIONAL TESTS IN CERTAIN CASES, AND THE NEED TO CONSIDER AMENDMENTS TO SPECIFICATIONS WITH RESPECT TO ACCEPTANCE REQUIREMENTS AND METHODS OF TEST. /TRRL/
