WATER-ABSORPTION PREVENTING MATERIAL AND METHOD FOR PREVENTING WATER-ABSORPTION OF CONCRETE MEMBER
PROBLEM TO BE SOLVED: To provide a water-absorption preventing material in which the application amount can be quantified easily and accurately, and to provide a method for preventing water-absorption of a concrete member by using said water-absorption preventing material.SOLUTION: Provided are: a water-absorption preventing material containing at least one main agent selected from a silane compound and a siloxane compound, and a labelling particle containing a particular element detectable by a fluorescent X-ray analysis method, the labelling particle satisfying, in a particle diameter distribution measured by a laser diffraction scattering method, the following formula (1); and a method for preventing water-absorption of a concrete member by using said water-absorption preventing material. D90/D10<30 (1). [D90 is a particle diameter corresponding to a cumulative percentage of 90% on the basis of a volume; D 10 is a particle diameter corresponding to a cumulative percentage of 10% on the basis of a volume.].SELECTED DRAWING: Figure 3
【課題】塗布量を簡便に、且つ正確に定量できる吸水防止材、およびその吸水防止材を用いたコンクリート部材の吸水防止方法の提供。【解決手段】シラン化合物およびシロキサン化合物から選ばれる少なくとも１つの主剤と、蛍光Ｘ線元素分析法により検出可能な所定の元素を含む標識粒子と、を含み、標識粒子は、レーザー回折散乱法によって測定される粒子径分布において、下記式（１）を満たす吸水防止材。及び、該給水防止材を用いたコンクリート部材の給水防止方法。Ｄ９０／Ｄ１０＜３０（１）［Ｄ９０は体積基準の累積百分率９０％相当粒子径；Ｄ１０は体積基準の累積百分率１０％相当粒子径］【選択図】図３
