The purpose of this paper is to investigate the propeties of Super Workable Concrete that was added chemical admixture after mixing. Super Workable Concrete which has the property of selfcompacting is being widely used for various structure, but often causes a decrease of slumpflow and a incease of funnel flowing time with passage of time or fluctuation in surface moisture content of fine aggregate.
In this paper, it considered about two methods of adding after mixing for the resoration of self-compacting. One was the addition a suitable amount of superplasticizer to the concrete of high powder content type decreased of slumpflow. The other was the method for viscous agent type that poured the mixture dissolved viscous agent in part of water and superplasticizer into concrete by mixing and excluding them. Both methods was clearly to be able to resore the properties of self-compacting and pumpability.
