【摘要】 结构中的混凝土实体强度与标准养护强度是有差别的,施工质量验收规范已提出了用同条件养护试件强度检验实体强度的要求。通过对唐山地区同条件养护混凝土试件强度的系统试验研究,探讨了其增长规律,并在此基础上建议了反映实体强度的同条件养护试件强度检验的等效养护龄期及强度折算系数。更多还原

【Abstract】 There is difference between solid strength of concrete structure and 28days’ age-strength in standard curing condition. Code for acceptance of constructional quality of concrete structures sets requirements that the structure strength should be inspected by the strength of specimens cured in the same condition. This paper discusses the growing rules for strength of pumped concrete at Tanshan area and gives out an entity strength test effective-curing-age and strength-converting-coefficient by a systematic experiment and test on pumped concrete in Tangshan area. It could be a reference for concrete entity strength test at Tangshan area.更多还原
