Abstract

Recently, structures become higher, larger and more strengthened. Mat concretes are planned and designed as mega foundations. This trend raises problems of concrete hydration heat and workability during construction. The two major issues of concrete quality in mega foundation construction are the control of hydration heat and improvement of workability. In this study, ternary blended low heat cement was developed to control hydration heat. Self compacting concrete and high performance concrete were also developed to assure concrete quality and workability. In addition, the biggest mock up test locally, 4m×4m×4m size, was performed to verify the performance of developed concrete. Several tests were carried out such as temperature measurement, slump flow test, compressive strength, tensile strength test, and crack investigation in this mock up test. Therefore it is inferred that the developed high performance concrete will be made full use for mega foundation construction.
