The towers were being made utilizing reinforced concrete, which permitted to the special curved types and cantilevered balconies that outline the creating's look. The use of reinforced concrete in Marina City was crucial in achieving its ground breaking style and design and structural integrity.
Concrete formwork might be geared up in numerous ways, for instance slip forming and steel plate building. Alternatively, concrete can be combined into dryer, non-fluid sorts and Utilized in manufacturing unit settings to manufacture precast concrete products and solutions.
The mix layout depends on the type of composition remaining designed, how the concrete is combined and delivered, And the way it is actually put to kind the framework.
