摘要
水泥砼面层以抗折强度作为强度检验和评定的首要指标。该文着重对配合比各组分原材料、搅拌及施工工艺、试验方法、试件成型方式、检验和试验人员素质等几个主要因素对抗折强度的影响进行探讨 ,同时对抽样的一部分数据进行了统计分析。
Bending strength is a critical index for inspection and evaluation of cement concrete facing. With statistic analysis of sampled data, this paper studies some key factors affecting that strength, such as the raw materials of constituents for the mix, the workmanship of mixing and construction, test methods, specimen formation and the quality of inspecting and testing persons.
