摘要
本文基于某地一新建混凝土框架结构项目实体检验等相关数据,针对游离氧化钙(f-CaO)对混凝土质量影响检验项目,对其芯样抗压强度等检验结果进行了数据整体分析。分析结果显示,在实际工程检验操作过程中,需针对现场情况可通过调查和检查混凝土外观质量初步确定f-CaO对混凝土质量是否产生了相应的影响;当检验数据接近标准《建筑结构检测技术标准》(GB/T 50344—2004)和《混凝土结构现场检测技术标准》(GB/T 50784—2013)中规定的限值情况时,需考虑检验过程中不能避免的人为误差影响。另外当抽取样本数量不足以明确进行结论判定时,需采取再次加倍现场取样检验,或采取其他检测手段进行平行验证。
Based on the relevant data of a new concrete frame structure project entity inspection etc;aiming at the inspection items of the impact o£free calcium oxide(f-CaO)on the quality of concrete,the overall data analysis of the compressive strength of the core sample and other inspection results is carried out in this paper.The analysis results show that in the actual project inspection operation process,it is necessary to preliminarily determine the impact of f-CaO on the concrete quality through investigation and inspection of the concrete appearance quality according to the site conditions.When the inspection data is close to the standards of technical standards for technical standard for inspection of building structure(GB/T 50344—2004)and technical standard for in-situ inspection of concrete structure(GB/T 50784—2013),the influence of human error that cannot be avoided in the inspection process shall be considered.In addition,when the number of samples taken is not enough to determine the conclusion clearly,,it is necessary to double the field sampling inspection again,or take other detection methods for parallel verification.
