Improving concrete setting for the construction of Marina Coastal Expressway
Marina Coastal Expressway C482 Project is the largest contract ever awarded by the Land Transport Authority. Under this project, the mass castings to the base slabs and top slabs of the tunnels present huge challenges, with six hours of retardation needed along with a concrete placement temperature not higher than 32 degree celcius. Singapore’s hot weather often induces loss of workability in concreting tasks.
