苏丹北科尔多凡州混凝土强度推定公式建立

本文通过搜集工程实例中混凝土早期强度数据,根据对数据的分析整理,利用回归法建立苏丹北科尔多凡州地区的早期普通混凝土强度推定公式,结果表明该推定公式能够较好的满足《早期推定混凝土强度试验方法标准》(JGJ/T15-2008)中规定的要求。在工程实践中,能较好的推测混凝土的28d强度。

Establishing the strength presumption formula of concrete in North Kordofan of SUDAN

This paper collects many data of Early age strength of concrete from many project cases.According to the analysis of these data, used regression method to establish strength constructive formula of early ordinary concrete of North Kordofan in Sudan. The results show that the constructive formula can better meet the standards in Early Strength of Concrete Test Method Standard （JGJ/T15-2008）.The strength of concrete after curing 28 days could be predicted better in projects
