a quick-setting (flash-setting)cement and a no(?)mal-setting cement were systematically studied for the difference in petrographic structure of clinker, their hydration and hardening of cements.
着重观测了快(闪)凝与正常凝的水泥熟料的结构和水化过程的显着差别。
by means of sem, edax and om, the petrographic structure and microscopic chemical composition of cement clinker have been researched by adding rare-earth lean ore.
