前言混凝土建筑物,受施工、地质、温度等因素所形成的应力影响,常出现深度不一的裂缝,往往是水泥灌浆所不能解决的,须用化学灌浆充填粘结,使混凝土得到补强,防止钢筋锈蚀,恢复其整体性。 Preface Concrete buildings are affected by the stress caused by construction, geology, temperature and other factors. Cracks of various depths often occur. These are often not solved by cement grouting and must be filled with chemical grouting to reinforce the concrete. Prevent corrosion of steel bars and restore their integrity.
