Summary:Numerous skyscrapers are being built using reinforced concrete construction in Dubai, UAE. Because the use of high-strength concrete is advantageous for skyscrapers from a number of aspects, concrete with a 100 N/mm2 compressive strength was produced using materials locally available, and its properties while fresh and after hardening were investigated. Its placing performance in a mock-up column and in-situ strength development were also examined to investigate its applicability to actual construction. As a result, it was confirmed that the properties of fresh concrete are retained with little change over the required period, and that hardened concrete presents good mechanical and durability properties. Mock-up testing also revealed that the placeability of the concrete was sufficiently good, and the compressive strength and elastic modulus of cores drilled from the mock-up were found to be satisfactory for concrete of compressive strength of 100 N/mm2.
