0前言混凝土构筑物的细裂纹分为混凝土劣化产生的细裂纹和混凝土收缩产生的初期细裂纹两类。对因劣化产生的细裂纹的修补方法,根据劣化的成因和劣化程度的不同而不同。例如,因盐害产生的细裂纹,因为盐化物离子深度侵蚀,防水修补前必须进行脱盐处理。尽管如此,再次劣化的可能性仍然很高。
0 Preface Fine cracks in concrete structures are divided into two categories: fine cracks caused by concrete deterioration and initial fine cracks caused by concrete shrinkage. The method of repairing a fine crack due to deterioration varies depending on the cause of deterioration and the degree of deterioration. For example, due to salt damage caused by fine cracks, salt ions because of the depth of erosion, waterproof repair must be desalination. In spite of this, the possibility of deterioration again is still high.
