预防耐久性混凝土收缩裂缝研究

On Prevention of Shrinkage Crack in Durable Concrete

耐久性混凝土产生裂缝,导致其性能与原状混凝土性能差异很大,加上混凝土裂缝又引起的各种渗透,会促使混凝土的进一步恶化,严重影响混凝土结构的耐久性,工程质量存在隐患。因此,必须对混凝土裂缝加以严格控制,探讨裂缝产生的原因及其预防措施。

Cracks in durable concrete may result in a dranmtic difference between the performance of the cracked concrete and that of the original concrete. In addition, various infiltration caused by concrete cracking leads to further deterioration of concrete, and the durability of the concrete structure is severely affected, leaving hidden dangers in security and quality. Therefore, concrete cracks must be strictly controlled, and discussion on reasons for such cracking and relevant preventive measures show great importance as well.
