摘要
对水泥混凝土试件采取喷涂养生剂的方式进行养生,龄期结束后,在喷涂养生剂的试件表面重新浇筑水泥混凝土/沥青混凝土,然后采取压缩抗剪的测试方式进行试验。结果表明,新旧水泥混凝土层间黏接强度仅下降4.2%,仍满足GB 50728—2011《工程结构加固材料安全性鉴定技术规范》中附录N"混凝土对混凝土黏接的压缩抗剪强度测定方法及评定标准"要求,水泥混凝土和沥青混凝土层间黏接强度则出现微量增长。
This paper treated the cement concrete specimens to cure by adopting the way of spraying curing agent. After the phase, it repoured the cement concrete or asphalt concrete on the surface of the sample sprayed with curing agent. Then it also carried out the test by means of compression shear resistance.
