However, I began setting time-limits for myself.

不过，我开始为自己定了时间限制。

The setting time and soundness of samples accord with request.

凝结时间和安定性均符合要求。

The accelerator can shorten the setting time, the dosage yet can not be too much.

早强组分可缩短水泥凝结时间，但掺量不宜太大；

Cement that has no additives to modify its setting time or rheological properties.

没有添加外加剂去改变其稠化时间或流变性能的水泥称之为净水泥。

Potassium sulfate accelerate the speed of the reaction, thus it reduce the setting time.

硫酸钾能加速凝固反应速率，缩短凝固时间。
