常見例句雙語例句The tensile stress induced by restrained thermal and autogenous shrinkage deformations was the main driving force of cracking in concrete at early age.溫度變形和自生收縮變形等受約束形成的拉應(yīng)力，是引起混凝土早期開裂的主要驅(qū)動力；By these experience, the paper firstly brought forward three concepts: turning point of autogenous shrinkage of concrete, continue maintain time, fly ash concrete strength balanced point.通過試驗研究文中首次提出了三個概念：混凝土自生收縮的轉(zhuǎn)折點、繼續(xù)養(yǎng)護時間、粉煤灰混凝土強度平穩(wěn)點。The experimental results show that SCA could either restrain the early autogenous shrinkage of paste or improve the prolonged shrinkage of concrete.結(jié)果表明：復(fù)合礦物外加劑可抑制混凝土自收縮變形，并使混凝土長期收縮變形得到補償。 返回 autogenous shrinkage
