A low heat cement high-fluidity concrete was applied to the abutment test wall and bed of our research institute in order to confirm the applicability of high-strength concrete to the mass concrete constructions with a highly crowded rebars. As a result, the high-strength high-fluidity concrete using low heat cement showed good fill capability and no cracks after the hardening. It can be concluded that the application of high-strength high-fluidity concrete with low-heat cement to a mass concrete construction, whose compaction is almost impossible due to a crowded rebar arrangement, was quite satisfactory.
