rapid hardening cement

The results show that lignin sulfonate coagulation time of COP rapid hardening high strength cement.

将绝热量热计与微机联用,研究了木质素磺酸盐对COP快硬早强水泥水化速率的影响.

To protect drilling normally drillers adopted mud ball plugging fill in plugging rapid hardening cement partial seal off 191# resiniferous cement plugging and high-pressured cement grouting successively.

为保证正常钻进，先后采用了制球堵漏、镶嵌堵漏、快干水泥局部封堵、191树脂水泥封堵和水泥高压注浆封堵。

The results show that lignin sulfonate serves the good function as reqlllating the coagulation time of COP rapid hardening high strength cement.

将绝热量热计与微机联用，研究了木质素磺酸盐对COP快硬早强水泥水化速率的影响。
