基本解釋

Expansive cement paste and joint concrete are next. And the bond splitting tensile strength of joint surface without bond material is least.
其次是水泥膨漿和接縫混凝土，接縫面不鋪筑任何接縫面材料的試塊，劈裂抗拉強(qiáng)度最小。
This paper has made a thorough study on its properties and delved further into its mechanism of compensation on cement concrete shrinkage by adding concrete expansive agent.
本文通過(guò)在普通混凝土中摻加膨脹劑對(duì)補(bǔ)償收縮混凝土的性質(zhì)進(jìn)行了研究，并就膨脹劑對(duì)混凝土補(bǔ)償收縮的機(jī)理進(jìn)行了探討。
