本文报道了一项研究的结果进行评估的效果养护收缩和抗腐蚀性的OPC和硅灰水泥混凝土。混凝土试样通过覆盖湿粗麻布或应用以下固化化合物之一来固化：水、丙烯酸、沥青基或煤焦油环氧树脂。结果表明，所选用的养护剂能有效地降低OPC和硅灰水泥混凝土的收缩应变，提高其抗腐蚀性能。还注意到，OPC混凝土在施用养护剂之前需要3d的湿麻布养护，而硅灰水泥混凝土需要7d的湿麻布养护。
This paper reports the results of a study conducted to assess the effect of curing on shrinkage and corrosion resistance of OPC and silica fume cement concretes. The concrete specimens were cured by covering with wet burlap or applying one of the following curing compounds, water-, acrylic-, bitumen-based, or coal tar epoxy. The results indicated that the selected curing compounds were effective in decreasing the shrinkage strain and enhancing the corrosion resistance of both OPC and silica fume cement concretes. It was also noted that 3days of wet burlap curing prior to the application of a curing compound was necessary for the OPC concrete while 7days of wet burlap curing is required for the silica fume cement concrete.
