Admixtures produced by Chryso are adding vital workability and fluidity to the concrete used for the construction of the new multi-billion dollar Qatar airport.

Ian Owen, technical manager, chemicals, for Corrotech, Chryso’s Dubai agent, says two Chryso admixtures have been specified for the concrete mix for the New Doha International Airport (NDIA), which is being built on 18 sq km of land reclaimed from the sea.
“Chrysoplast ME210 is being applied to extend the workability of the concrete for the airport project, with Chrysofluid ME505 adding fluidity to the mix. The chemicals were specified after extensive trials,” he says.
Owen adds: “A total of 2 million cu m of concrete will be used for the construction of a new terminal building, two runways, a business park, and full airport infrastructure at Doha.
“Around $2.5 billion has been invested in the first phase, with another $5 billion earmarked for the second and third phases. Work has recently started on the project, the Phase I of which is scheduled for completion in 2008. The project is expected to be fully complete by 2015.
“The main contractors include Bechtel Group – handling the design and engineering aspects – and Al Jabar Tremix – producing and supplying the concrete. The airport is expected to carry about 12.5 million passengers per year by 2008 and 50 million per year in 2015. The present airport now handles about four million passengers per year.
The national airline, Qatar Airways, will relocate its headquarters and training facilities to the new Doha airport, which is expected to become the new “hub” of the Middle East.
 
The Pearl-Qatar
A “new generation” admixture from Chryso forms an integral part of the concrete mix being used for the construction of Qatar’s largest real estate project to date, The Pearl-Qatar island development.
The project is a large man-made island of around 400 hectares situated about 350 m off the coast of Doha, the capital of Qatar. It is being developed by the United Development Company (UDC), Qatar’s largest private sector shareholding company.
Chrysofluid Optima 250 new generation admixture is being supplied for the production of about 100,000 cu m of concrete needed for the massive project. “Optima 250 is providing extended workability as well as durability to the concrete being produced in ready-mix form at the Al Wataniya plant in Qatar,” says Owen.
The Pearl-Qatar will, when completed at the end of this year, house about 30,000 people in over 7,600 homes located in 10 unique precincts. It will accommodate at least three luxury hotels, entertainment and recreational facilities, four marinas with mooring for 700 boats, schools, community centres, and public parks. Retail and restaurant space of over 60,000 sq m has been provided.
The development is the first in Qatar to offer freehold and residential rights to the international community, with the first residents scheduled to move in this September.
Chryso last year added a new reactor, providing more capacity for the manufacture of their new generation PCP’s. The move has found favour with many concrete manufacturers globally. The new reactor has enabled users in having the ability to pump concrete vast distances both vertically and horizontally. The company’s Optima 100 has been included for use on part of the Dubai Metro and for the expansion of a major aluminium manufacturer.
Corrotech’s new state-of-the-art manufacturing facility, which is nearing completion at the Dubai Investment Park, will include an automated manufacturing plant, as well as a liquids blending and powder blending plant.
