CONCRETE STRUCTURE REINFORCING METHOD
PROBLEM TO BE SOLVED: To reinforce a concrete structure with sufficient strength in a short time by using an inorganic system injection material.SOLUTION: An inorganic injection material is made by mixing ultrafine particle cement, water, and silicic acid system additive. The inorganic injection material is injected and cured in a cavity generated in a concrete structure (concrete block 1). In the inorganic injection material, mixed weight ratio of the mixture liquid of the water and silicic acid system additive to 1 of the ultrafine particle cement is set to within 0.4 to 0.7, and mixed weight ratio of the silicic acid system additive to 1 of the water is set to within 0.3 to 0.5. The inorganic injection material is injected in the cavity at a pressure higher than 0.1 N/mm2 and equal to 0.4 N/mm2 or less.SELECTED DRAWING: Figure 1
【課題】無機系の注入材を使用して短時間に十分な強度でコンクリート構造物を補強する。【解決手段】超微粒子セメント、水およびケイ酸系混和剤を混合してなる無機注入材をコンクリート構造物（コンクリート製ブロック１）に生じた空隙内に注入し硬化させる。無機注入材において、超微粒子セメント１に対して水とケイ酸系混和剤の混合液の混合重量割合を０．４〜０．７の範囲とし、かつ水１に対してケイ酸系混和剤の混合重量割合を０．３〜０．５の範囲として、前記無機注入材を０．１Ｎ／ｍｍ2を超え０．４Ｎ／ｍｍ2以下の圧力で前記空隙内に注入する。【選択図】図１
