Abstract:
In the construction of the foundation slab of Terminal T3B Project at Beijing Capital International Airport, fly ash and fine slag powder were used, and the quantity of cement was reduced to lower than that of the code, without anti-freezing agent being admixed. Various effective measures were taken to prevent cracks in the construction from the selection of raw materials to the control of construction process, including pouring concrete layer by layer, repeated troweling and moist curing and etc. No serious crack was found in the completed foundation slab.
