Hyperstrength Cement Testing.

Abstract

This is the final report of an investigation whose objective was to measure and evaluate the mechanical properties of a hyperstrength cement mixture consisting of a hydraulic cement and a water-soluble polymer. Plate samples were prepared using a twin-mill operation, followed by cold pressing and oven drying in the research and development facility of the Mond Division of Imperial Chemical Industries, PLC. The material has unusually high static tensile strength for a cementitious material, but it is very brittle. The testing program included standard static tensile, compressive and flexure tests to determine moduli, elastic limits and ultimate strengths and fracture toughness tests. Effects of moisture and thermal environment were investigated. Dynamic tests included high-strain-rate compressive tests with a split Hopkinson's pressure bar system, dynamic modulus by vibration and by wave propagation, and damping by vibration tests. Ballistic impact tests are also reported.
