PURPOSE:To provide the subject hydraulic grouting material for grouting into the ground or for repairing fine cracks such as a crack of a concrete building. CONSTITUTION:A hydraulic grouting material characterized by its composition containing a blast furnace slag, calcium aluminate and slaked lime and its particle size of <=32mum maximum particle diameter and <=5mum average particle diameter. By using the above-mentioned hydraulic grouting material, the grouting property, especially into fine cracks is improved and manifestation of short- and long-term strength can be improved. Chemical resistance is improved and shrinkage is reduced. Reverse outflow to the concrete wall surface and bleeding are prevented and cavity after grouting and curing can be prevented. The hydraulic grouting material in this invention shows the above-mentioned effects. |
