| 摘 要： | 为了研究水泥混凝土路面抗滑构造对抗盐冻剥落的影响,采用5种不同抗滑构造,进行抗盐冻剥落试验。结果表明,对普通混凝土,拉粗毛和中毛时试件剥落最多,剥落量比光面混凝土大20多倍,刻粗槽和拉细毛其次,而刻细槽剥落量最小;通过掺加引气减水剂,剥落量可明显减少。因此在北方地区,作抗滑处理的混凝土应掺加引气减水剂,并尽量采用刻细槽,不宜采用拉槽工艺。

| Abstract: | In order of studying the effect of skid-resistant texture on salt freezing resistance of cement concrete pavement,salt freeze tests are made for five kind of skid texture.Results indict for common concrete,scaling of brooming medium and thick texture specimens are most.The scaling mass is 20 times of smooth surface specimens.Mixing air-entraining and water-reducing agent into cement concrete,scaling mass of concrete are reduced obviously. |
