Al Warrak Bridge 

Al Warrak Bridge, built by Arab Contractors, Egypt's largest contracting company, is the largest crossing of the River Nile in the Greater Cairo region.

The project had special concrete requirements for extended workability retention, high slump for ease of placing and high early strength to allow demoulding of forms.

Rheobuild 1100, a type F naphthalene based admixture, was chosen to meet the requirements for strong plasticising action and high early strength development.

Extensive use was also made of Rheobuild 561E, a type G retarding superplasticiser, where longer workability was desired.

BASF supplied over 320,000 litres of admixture to support the construction of this bridge.

Rheobuild 1100 is a flagship superplasticiser developed by BASF Middle East Dubai with more than 10 years history, and Rheobuild 561E is developed from the long famous Rheobuild 561 used for many years in Italy.

BASF  enjoys a number one position in admixture supplies world-wide; this position is supported strongly by continued investment in major research centres in Europe, the States and the Far East.
