THE ROLE OF MOTAR-AGGREGATE BOND IN THE STRENGTH OF CONCRETE

MORTAR-AGGREGATE BOND IN CONCRETE IS DEFINED AND FACTORS WHICH INFLUENCE THE BOND ARE DISCUSSED. THE DISCUSSION IS BUILT AROUND ORIGINAL WORK BY THE AUTHOR AND WORK PUBLISHED BY OTHERS. THE ROLE WHICH MORTAR-AGGREGATE BOND APPEARS TO PLAY IN THE MECHANISM OF CONCRETE FAILURE IS DISCUSSED. PARTICULAR EMPHASIS IS GIVEN TO THE RELATIONSHIP OF MICROCRACKS AND MORTAR-AGGREGATE BOND. THE NECESSITY OF MEASURING BOND WITH SATURATED SPECIMENS, TO PREVENT DRYING SHRINKAGE STRESSES, PRODUCES RESULTS WHICH MAY NOT BE REPRESENTATIVE OF THE BONDS IN CONCRETE. CONSIDERATION OF WHAT INFLUENCES BONDS IN NORMAL CONCRETE IS GIVEN. THE EFFECT OF DIFFERENT MEASURED MORTAR-AGGREGATE BOND STRENGTH ON THE STRENGTH OF CONCRETE IS DISCUSSED WITH DATA PROVIDED.
