粉煤灰陶粒混凝土的弹性恢复和徐变恢复特征

The characteristic of elastic and creep recovery of sintered fly-ash concrete

对粉煤灰陶粒混凝土在三种持续应力水平下的弹性恢复和徐变恢复进行了实验研究。结果表明,粉煤灰陶粒混凝土卸载后,其弹性恢复均大于按不受荷伴随试件的弹性模量计算的恢复值,徐变恢复也大于普通混凝土。

The elastic and creep recovery of the sintered flyash concrete under three sustained stress level is measured.The results of this research show that the elastic recovery of loaded sintered flyash concrete is at any time greater than that of the calculated elastic modules of the same concrete without loading.The creep recovery is also greater than that of normal weight concrete.
