Abstract:Because of the alkali reactivity with cement,there is potential harm for the sand and aggregate taken from northern branch of Jumahe River.Measures to inhibit of alkali reactivity must be taken for the sake of structure durability.The long distance concrete structure and continuous construction technology without cracks are adopted in the fore tank and buildings.The structure can be ensured by considering the temperature control measures.These measures play big roles to shorter the construction period and cut off the cost as while as guarantee the structure""s durability and safety.

 

Key words:Huinanzhuang pump station;alkali aggregate reactivity;expansive concrete;temperature control
