In recent years, admixtures with viscosity agent have been developed and are increasingly being used, mainly in the field of civil engineering. In the construction sector, where many restrictions such as the Building Standards Law and JIS standards apply, on-site application requires consultation regarding concrete quality control and quality assurance for the required performance among the construction supervisors, ready-mixed concrete plants, and construction companies. This time, we had the opportunity to apply superplasticized concrete with viscosity agent controlled by slump flow to construction. This paper reports on the application processes and quality control involved when applying superplasticized concrete controlled by slump flow to main structural parts in buildings.
