水泥混凝土的白瘢病及其治理

The white scar on the surface of concrete and its treatment

分析了水工混凝土表面发生白瘢病的溶蚀破坏是含钙水泥中的钙质和CO2及工程质量和冻融的联合作用下发生的一种混凝土溶蚀破坏问题。提出采用富含CiO2的硅粉材料拌制水泥净浆、水泥砂浆、水泥混凝土,通过中和水泥中的多余游离钙质,抑制水泥中钙质的流失,并控制混凝土白瘢病继续发展。

This paper analyses the dissolve erosion destroy of the white scar on the surface of hydraulic structure concrete which is a kind of concrete dissolve damage occurred by the combining action of the calcium and CO2 in the cement , and the project quality and frost and thaw. Silicon power Rich contained CiO2 is used in cement slurry and cement sand slurry and cement concrete, counteract the spilth dissociate calcium, to control the calcium erosion and restrain the white scar development.
