The towers had been built working with reinforced concrete, which allowed for your exceptional curved types and cantilevered balconies that determine the creating's physical appearance. The usage of reinforced concrete in Marina Metropolis was vital in achieving its revolutionary style and structural integrity.
Bonding brokers are employed to create a bond in between old and new concrete (normally a form of polymer) with extensive temperature tolerance and corrosion resistance.
[78] The conversion of calcium hydroxide inside the concrete into calcium carbonate from absorption of CO2 about quite a few many years further more strengthens the concrete and causes it to be more proof against harm. This carbonation reaction, nevertheless, lowers the pH with the cement pore Alternative and can corrode the reinforcement bars.
