摘要
按国家标准浇铸油井水泥试块,养护24h后测其声阻抗及抗压强度。实验表明,水泥试块在水灰比为0.38～0.62时,水泥试块的声阻抗与抗压强度间呈非线性关系。养护时间不同,其抗压强度有明显的差异。
The examined cement specimens were cast according to the national standard,and the acoustic impedance and compressive strength of the specimens after curing for 24 hours were measured.It was found that a nonlinear relationship existed between the two physical parameters,when water and cement ratio was 0.38~0.62.The compressive strength also varied with the curing time.
