Tuas Undersea Cable Tunnel

The Tuas Undersea Cable Tunnel project was the first of its kind in the region considering the complexity of construction and the quality/performance of concrete required. The project involved the construction of a reinforced concrete tube about 2.1km long placed on the ocean bed for carrying power supply cables from 2 large new installations on the Tuas peninsula on the western side of Singapore, across Tuas Bay to electrical sub-stations at Ayer Rajah and Labrador in Southern Singapore.

Specification requirements on the concrete encompassed numerous high performance criteria, ranging from temperature control, low w/c ratio and high slumps on fresh concrete to high early strengths, low permeability and high durability on hardened concrete.

High Slag Portland Blast Furnace Cement (HSPBFC), with a fixed proportion of 30% Ordinary Portland Cement (OPC) and 70% Ground Granulated Blast Furnace Slag (GGBS) was used to reduce heat of hydration of thick sections and to provide better marine durability characteristics especially with regards to chloride and sulphate attacks.

An estimated 23,520 tons of VCEM was used in this project.

KK Women's and Children Hospital

KK Women's and Children's Hospital, or simply KKH, is the largest medical facility in Singapore providing specialised care for women, babies and children and it is the only integrated women's and children's hospital in Singapore. Housed in its new premises at 100 Bukit Timah Road which was completed in 1997, the hospital includes Singapore’s first and only purpose-built Children’s Hospital. Low heat concrete was specified for this project and the area of application is in the foundation - pile caps.

Rantembe Dam Project
The Rantembe Dam Project involved the construction of thick concrete sections and submerged structures. Concrete used to make such structures must fulfill stringent temperature and durability requirements. These are- control of the temperature rise in concrete which reduces the peak temperature and thermal cracks; prevention against the corrosion of steel bars by controlling the intrusion of chloride ions and prevention against sulphate attacks.

After the consultant’s in-depth study, SsangYong High Slag Portland Blastfurnace Cement, P4246, was concluded to possess good peak temperature reduction, better consistency, setting time and strength development, thus meeting the stringent specifications.

In addition, P4246 was found to be superior in terms of product attributes and quality when compared with other international slag cement suppliers from
Belgium, Germany and Japan, etc. The project was constructed during year 1987 to 1989.

Note: P4246 is a homogeneous blend of Ordinary Portland Cement(OPC) and VCEM.

Jinan Kaiyuan Tunnel
VCEM was used in Jinan Kaiyuan Tunnel, which is designed to be the arterial road in the town. It is the longest tunnel of its kind in Shandong province as well as in China. The tunnel is divided into 2, whereby the length of each tunnel is 1500m, for a total construction length of 3000m. The width and height of the tunnel is 13.05m and 7.8m respectively. The road surface in the tunnel was paved with concrete cement thickness of 25cm.
