THE THEORETICAL PREDICTION OF THE CRACKING STRESS OF GLASS FIBRE REINFORCED INORGANIC CEMENT

PREVIOUS RESEARCH HAS DEMONSTRATED THAT THE STRENGTH OF HIGH-ALUMINA CEMENT REINFORCED WITH GLASS FIBERS DOES NOT DETERIORATE WITH TIME OWING TO POSSIBLE ATTACK ON THE FIBERS BY ALKALIS OF THE CEMENT PASTE; IN ADDITION, AN ALKALINE- RESISTANT GLASS THAT CAN BE USED WITH PORTLAND CEMENT HAS BEEN DEVELOPED. FROM THIS RESEARCH IT BECAME APPARENT THAT THE GOVERNING VALUE OF STRESS IN THE DESIGN OF ANY STRUCTURAL COMPONENT WOULD BE THE CRACKING STRESS RATHER THAN THE ULTIMATE TENSILE STRESS, SINCE BEYOND A GIVEN POINT ON THE STRESS--STRAIN CURVE IRREVERSIBLE DEFORMATION OCCURS AS A RESULT OF CRACK PROPAGATION. IN THE PRESENT PAPER A THEORETICAL PREDICTION, BASED ON FRACTURE MECHANICS, IS PROPOSED FOR THE CRACKING STRESS OF FIBER-REINFORCED INORGANIC CEMENT, AND THE RESULTS OF EXPERIMENTS CONDUCTED TO TEST THE HYPOTHESIS ARE PRESENTED. THE PREDICTIVE METHOD WAS FOUND TO BE IN GOOD AGREEMENT WITH THE EXPERIMENTAL RESULTS.
