    • PROBLEM TO BE SOLVED: To provide a mortar for spraying not drooping even if increasing a water binder ratio, and having small electric resistance and small contraction, and to provide a corrosion prevention method by the same, for further reducing the contraction, maintaining the small electric resistance for a long period, and not disturbing permeation of chlorine gas or the like.SOLUTION: The mortar for spraying having the small electric resistance uses a mortar composition wherein a binder containing cement, fine aggregate, a water reducing agent, and water are blended, and can be obtained by adding an alkali thickening type polymer emulsion to a mortar having a no-tapping mortar flow value of 200-320 mm prepared by use of a mortar composition having the water binder ratio of 35-55% and a unit water amount of 250-400 kg/m, and has a contraction amount ≤-800×10. A hardened body of the mortar for spraying has electric resistivity ≤100 kΩcm. A mortar hardened body is formed by coating an organic-inorganic composite coating-film curing agent on the surface of the hardened body of the mortar for spraying. The corrosion prevention method for steel material inside a concrete structure uses the mortar hardened body.
    • 要解决的问题:即使增加水粘合剂比例,并且具有小的电阻和小的收缩,也可以提供一种不下垂的喷雾砂浆,并提供一种防腐蚀方法,为了进一步减少收缩, 保持长时间的小电阻,并且不妨碍氯气等的渗透。 解决方案:具有小电阻的喷雾砂浆使用其中混合含有水泥,细骨料,减水剂和水的粘合剂的砂浆组合物,并且可以通过将碱增稠型聚合物乳液加入到 通过使用具有35-55%的水粘结剂比例和250-400kg / m 2的单位水量的砂浆组合物制备的具有200-320mm的无攻牙砂浆流动值的砂浆 3 ,收缩量≤-800×10 - 6 。 用于喷涂的砂浆的硬化体具有≤100kΩcm的电阻率。 通过在用于喷雾的砂浆的硬化体的表面上涂布有机 - 无机复合涂膜固化剂来形成砂浆硬化体。 混凝土结构内钢材的防腐蚀方法采用砂浆硬化体。 版权所有(C)2012,JPO&INPIT
