【摘要】 近年来轻集料混凝土在工程中的应用越来越广泛。通过对不同龄期(3、7、14、21、28d)试件的强度回归分析得出的各龄期抗压强度(fn)和龄期对数(lgn)的关系。在工程实践中,可以通过早期强度预测28d抗压强度。更多还原

【Abstract】 The application of light aggregate concrete in project is used widespreadly.The relationship between fn and lgn is obtained by strength regression analysis of sample at different ages(3?7?14?21?28d).The compression strength after 28 days can be predicted by early strength in engineering practice.更多还原
