摘　　要：同条件养护混凝土强度检验时等效养护龄期的确定是工程界普遍关注的问题之一。由于各地气候、混凝土原材料及施工管理水平的差异,不可一概而论地取成熟度达到600℃∙d时所对应的龄期作为混凝土强度检验时的等效养护龄期。基于此,通过对新疆维吾尔自治区某地区的试验数据进行汇总分析,研究同条件养护混凝土的早期强度发展情况,获得了混凝土同条件养护试件早期相对强度的拟合公式。利用该公式对混凝土同条件养护等效养护龄期进行了预测,获得了不同月份的混凝土同条件养护等效养护龄期值,对实际指导混凝土的实体强度检验具有现实意义。The determination of equivalent-curing-age for strength test of concrete under the same curing condition is a commonly concerned issue in engineering field.Due to the differences of climate,materials and construction management level in different areas,it is impossible to take the corresponding age at the maturity of 600℃·d as the equivalent-curing-age of concrete strength test.For this reason,the experimental data in a region of Xinjiang uygur autonomous region were used to study the early strength development of concrete under the same curing condition.The fitting formula of relative-strength of concrete specimens under the same curing condition was obtained and used to predict the equivalent-curing-age of concrete under the same curing condition and the equivalent-curing-ages of concrete under the same curing condition in different months were obtained.It is very important for offering real guidance to the physical strength test of concrete.
