Egypt: Suez Cement subsidiary Ready Mix Beton says that it has secured a contract for the supply of concrete for the construction of two new monorail lines projects. Due to begin in late-2020, the contract covers the construction of a monorail line between Cairo and the New Administrative Capital and another between 6 October City and Giza. The company says that it will use Suez Cement’s CEM III/A ground granulated blast furnace slag (GGBFS) cement to produce concrete for the 96km monorail network.

Suez Cement said, “CEM III/A cement is highly recommended when building thick concrete supports and massive structures because its hydration temperature of less than 210kJ/kg reduces cracking compared with Ordinary Portland Cement (OPC) when the applied concrete is subjected to dual exposure to sulphates and chloride ions, as happens in coastal areas.”

UK: Hanson supplied its Regen ground granulated blastfurnace slag (GGBS) product for use on part of the Thames Tideway Tunnel super sewer project in Wapping, London. The product was used to overcome difficult ground conditions. Around 5700t tonnes of Regen, supplied from its Purfleet grinding plant in Essex, was used with 3000t of Ketton cement to create a binder to stabilise soil so work to construct a combined sewer overflow could progress and provide a connection to the main east tunnel.

Costain, VINCI Construction Grands Projects and Bachy Soletanche worked with Hanson in laboratory trials to test the performance of the system and suitability of the selected mix design. Deep soil mixing, a technique that enhances the characteristics of weak soils by combining them with a cementitious binder, was chosen as the final stabilisation method.

The Thames Tideway sewer network expansion is due for completion in 2024 and is happening across 24 construction sites in London, spanning from Acton in West London to Beckton in the east of the city.

UK: HeidelbergCement’s subsidiary Hanson is supplying its Regen GGBS (ground granulated blastfurnace slag) cement replacement for a project to build a new tidal barrier across the New Cut River in Ipswich. The Euro24m project is being managed by the Environment Agency to protect properties at risk of flooding.

The work is being carried out by VBA, a joint venture between VolkerStevin, Boskalis Westminster and Atkins, and is due to be fully operational by September 2018.

Indonesia: Semen Indonesia has launched a new slag cement product under the brand ‘Maxstrength Cement.’ The cement producer said it was the first Portland Slag cement produced in the country. The company can producer 1500t/day of the slag cement and it is intended for use in large scale infrastructure projects that require high flexural strength, such as bridges or road flyovers.
