Precast Concrete Construction in Canada
Appears on pages(s):
Precast concrete construction techniques as applied to a warehouse, parking garage, and retaining wall project are described. Beams and columns for the precast frames of a warehouse were cast flat in multiple forms on the ground slab. Cold weather required special prequations in mixing, placing and curing the concrete. In a parking garage, precast elements were combined with cast-in-place members to form an essentailly monolithic structure. A retaining wall 25-ft high is of precast counterforts and 8-in. wall lanks. Principal featres of the job were the complicated shape of the counterforts and the weight if the completed units.
