某污水处理厂混凝土工程碱含量的控制

The control of the amount of alkali of concrete used in the project of a certain sewage treatment plant

介绍了污水处理厂混凝土工程,为预防混凝土工程碱—集料反应,选用低碱水泥和外加剂,掺加粉煤灰和低水泥用量等综合措施,制定科学配合比、使污水处理厂混凝土工程含碱量得到有效的控制。

The concrete used in a certain sewage treatment plant is introduced.To prevent the alkali-aggregate reaction from occurring,and to effectively control the amount of alkali of conerete used in projects of the sewage treatment plant,such measures are taken as choosing low-alkali cement and additive,adding coal ash and low amount of concrete and working out a scientific mixture ratio.
