摘 要：為解決目前混凝土早齡期變形試驗方法存在的缺陷（試模及潤滑油脂對混凝土收縮變形的約束、無法準確測得混凝土初凝前的變形），采用重液懸浮混凝土試件的方法來消除試模對試件的變形約束，研發了一種能準確測量混凝土早齡期變形的試驗裝置。結果表明：通過該試驗裝置測得的數據具有一定的準確性。
Abstract: In order to overcome the defects of existing test methods(mould and lubricating oil restrict shrinkage of concrete, and cannot accurately measure the deformation before the concrete initial setting), a new testing apparatus for early-age concrete unconstrained deformation was developed for using suspension heavy-liquid ?in eliminating the restriction of mould. The results show that the data by testing apparatus has certain accuracy.
