混凝土强度恢复能力试验研究

Experimental Study on Recovery of Concrete Strength

通过在水泥砂浆试件中掺入矿物质,测定矿物质对混凝土抗折强度的影响。在矿物质最佳掺量条件下,加入修复液,测其强度恢复率。通过试验对比,可以得出修复液的添加对混凝土微裂纹的修补起到了很好的作用,利用矿物与修复液的共同作用可以修复微裂纹,有利于混凝土抗折强度的恢复。

Through mixing minerals into the cement mortar specimen, the effects of minerals on the flexural strength of concrete are tested. In conditions of optimum adding amount of minerals, adding the repair liquid, the strength recovery rate is tested. And by comparison, adding repair fluid may be played a very good role on the micro crack repair of con- crete, and both adding minerals and repair liquid can repair micro cracks, which is conducive to the recovery of concrete＇ s flexural strength.
