ROLE OF THE INTERFACE IN GLASS FIBRE REINFORCED CEMENT

GLASS FIBER REINFORCED CEMENT (GRC) PROVIDES AN INTERESTING EXAMPLE OF INTERACTION BETWEEN A BRITTLE FIBER AND A POROUS BRITTLE MATRIX WHICH IS REACTIVE TOWARDS THE REINFORCEMENT. IT IS ALSO A CASE IN WHICH THE COMPOSITE FAILS BY MULTIPLE FRACTURE. THE DURABILITY OF GRC PRODUCED FROM ORDINARY PORTLAND CEMENT AND AN ALKALI-RESISTANT GLASS FIBER RECENTLY DEVELOPED IN THE U.K., HAS BEEN STUDIED OVER A PERIOD OF THREE YEARS UNDER DIFFERENT ENVIRONMENTAL CONDITIONS BY MEASURING THE VARIATIONS IN THE MECHANICAL PROPERTIES OF THESE COMPOSITES WITH AGE. IT IS CONCLUDED THAT THE PROPERTIES OF THE INTERFACE IN GRC CHANGE WITH TIME, PARTLY DUE TO CHEMICAL ATTACK ON THE FIBER WHICH WEAKENS THE REINFORCEMENT, BUT ALSO DUE TO CHANGES IN THE PHYSICAL PROPERTIES OF THE FIBER BUNDLE AND POROSITY AND VOLUME CHANGES IN THE MATRIX AS IT SETS AND HARDENS.
