小型构造物混凝土表面粗糙原因分析及防治措施

Analysis on Coarseness Reason of Small Conformation Concrete Surface and Its Prevention

在公路工程施工中,小型构造物混凝土表面经常会产生粗糙的现象,通过研究发现影响混凝土外观质量的因素很多,而结构物外观设计、原材料及配比、施工、养护是能够改善外观质量的前提。

During the highway engineering construction,small conformation concrete surface is often coarse. As study shown,there are many factors affect the appearance quality of concrete,and the structural appearance design,raw materials and mix ratio,construction,and maintaining are all premises in improving appearance quality.
