Then it is followed by cementsetting and hardening and a cellular structure is formed in the concrete, which is called gas-carrier cellular concrete.
复经水泥凝结硬化在砼中形成一种多孔结构,这程砼称之为载气体多孔砼。

The cementsetting time at different temperatures has been measured through choosing citric acid, sugar and sodium gluconate as the retarders of iron Portland cement.
The results show that composite inhibitors have excellent corrosion inhibition efficiency and won't give bad effect on cementsetting time , flexural strength and compressive strength.
