摘要
在权重成熟度理念基础上,参考国外胶凝材料C值取值,结合国内现有的标准和设备,进行简化,建立混凝土早期强度预测公式,并应用该公式预测了相同混凝土不同养护条件下不同龄期的抗压强度。与实测强度比较,证明预测准确性高,可及时掌握混凝土早期强度发展情况。
Based on the weighted maturity concept and the C-value from literature review,the weighted maturity method has been improved and the strength prediction equation has been established in combination with the current standards and equipments.The strength development of the concretes,which were made with the same cement and cured under different conditions were predicted using the prediction equation.It is shown that the predicted results are very accurate compared to the measured values.
