| Abstract: | A 300 mm-thick layer of expanded-sand concrete was cast to insulate the tower foundation from low temperature attack. Commefical air-entraining agent was used when mixing conrete instead of self-made one. And effective measures were taken in the construction of concrete mixing, casting and curing, while constant weight specimens were also made for testing. Concrete properties satisfied the design requirements, and construction of the tower foundation was thus speeded up. |
