Rehabilitation of Deteriorated Agricultural Waterways due to Polymer Cement Mortar
Recently the deterioration and rehabilitation of waterways made of reinforced concrete as agricultural hydraulic structures are urgent issues. The main causes of deterioration of these waterways are peculiarly abrasion of concrete at the side wall and bottom slab due to the current containing fine sand particles, cavitation and water jet. The typical deterioration is exposure of aggregate, peeling off and corrosion of the surface, and cracks corresponding to the above causes. It is desirable for waterways after rehabilitation to ensure sufficient water supply capacity, high durability and strength of repaired materials. In this study, repair methods by use of epoxy resin primer and polymer cement mortar lining were investigated and effective countermeasure was proposed, and its trial construction was performed by the field test.
