The effect of water cement ratios on setting time (20 ± 2°C).

Water cement ratio	Type of cement	Initial setting time	Final setting time
0.35	Jidong cement	1 min 30 s	3 min 20 s
	Qinling cement	2 min	4 min 30 s
0.40	Jidong cement	3 min	6 min 50 s
	Qinling cement	3 min 30 s	7 min 20 s
0.45	Jidong cement	13 min 10 s	35 min
	Qinling cement	15 min	30 min 50 s
