Abstract

Recently, high-rise reinforced concrete buildings 145 and 112 meter in height were constructed using high strength concrete with specified design strength of 100MPa. This paper deals with scheme of work execution and the results of quality control tests used in the construction of these buildings. In addition to the conventional quality control tests such as flow and air content measurements, a newly developed method of measuring the unit water content on flesh concrete was employed. As a result, high strength concrete with stable quality satisfying the design strength requirement was obtained.
