After the completion of the engineering project, the hope cement hardening, as soon as possible to produce strength, so the final setting time shoulds not be too long.
施工完毕后，希望水泥能尽快硬化，产生强度，所以终凝时间不宜太长。
The results show: (1) with high calcium mixing, concrete workability was modified, the water quantity needed for standard consistence decreased, initial and final setting time increased;
结果表明：（1）高钙灰的掺入改善了胶砂的工作性，降低了标准稠度用水量，延缓了胶材的初终凝时间；
The initial setting time of Portland cement shall not be earlier than 45 minutes, final set time not later than 390 minutes.
硅酸盐水泥的初凝时间不得早于45分钟，终凝时间不得迟于390分钟。
