The Properties of Concrete(BlueCon) using Fluosilicate Salt Based Admixtures and Estimation of Field Application

This study was performed to know the properties and estimation of field application of concrete(Bluecon) using fluosilicate salt based admixture made from by-product during phosphoric acid manufacturing process. Mix proportions for experiment were modulated at 0.45 of water-binder ratio and $0.5-2.0\%$ of adding ratio of fluosilicate salt based inorganic compound. Evaluation for Field application of concrete was carried out batch plant test at remicon factory and building construction. According to results. it was found that slump of concrete(Bluecon) using fluosilicate salt based admixture is higher about 10 to 20 mm than plain concrete, and air content is similar to each other. And the water permeability and crack of bluecon is lower than that of plain concrete.
