METHOD FOR PRODUCING HYDRAULIC COMPOSITION AND HYDRAULIC COMPOSITION
PROBLEM TO BE SOLVED: To achieve both fluidity and fire resistance.SOLUTION: There is provided a method for producing a hydraulic composition comprising water, a binder containing cement and an organic fiber, which comprises: a step of determining an inflection point where the residual area rate in the fire-resistance test is not changed when increasing the amount of the organic fiber incorporated without changing a water-binder ratio which is the weight ratio of water and the binder; and a step of mixing an organic fiber higher than the inflection point with water and the binder in the water-binder ratio to produce a hydraulic composition.SELECTED DRAWING: Figure 4
【課題】流動性と耐火性の両立を図る。【解決手段】水と、セメントを含む結合材と、有機繊維とを含有した水硬性組成物の製造方法であって、水と結合材との重量比である水結合材比を変えずに、混入する有機繊維の量を増やしていき、耐火試験の残存面積率が変化しなくなる変曲点を求める工程と、変曲点以上の有機繊維を、前記水結合材比の水及び結合材に混合して水硬性組成物を製造する工程と、を有する。【選択図】図４
