ALUMINA FILAMENT REINFORCED CEMENT PASTE

ALTHOUGH CEMENT AND CONCRETE HAVE CONSIDERABLE COMPRESSIVE STRENGTH, THEIR VERY LIMITED RESISTANCE TO CRACKING UNDER THE INFLUENCE OF TENSILE FORCES RENDERS THEM UNSUITABLE FOR A NUMBER OF BUILDING APPLICATIONS. STEEL REINFORCEMENT AND PRESTRESSING ARE COMMONLY USED TO OVERCOME THIS, BUT ARE NOT ALWAYS ADEQUATE OR CONVENIENT. REINFORCEMENT WITH CLOSELY- SPACED FIBROUS MATERIALS SUCH AS STEEL WIRE, GLASS FIBER AND ASBESTOS, THEREFORE, HAS BEEN OF INTEREST RECENTLY. THE PRESENT WORK IS AN ATTEMPT TO ASSESS THE VALUE OF POLYCRYSTALLINE ALUMINA FILAMENTS IN THIS RESPECT. BY INCORPORATION OF A FEW PERCENT OF THEM ONLY, IT HAS BEEN POSSIBLE TO INCREASE THE MEAN ULTIMATE TENSILE STRENGTH OF CEMENT PASTE BY UP TO THREE TIMES, AND MEAN WORK OF FRACTURE BY A FACTOR OF MORE THAN TWO. /DOT/
