Significant acceleration of concreting

Description

The project is a major refurbishment of two concrete bridges along a busy arterial route in Leeds city centre.

Challenges

The challenge  was a bridge abutment measuring 6.5 meters in height and 2 meters in width, which had to be delivered in the unforgiving winter of the North of England. The critical factor that demanded utmost attention during the concreting endeavor was the rate of rise.

Solution and results

Cidon Construction relied on the PREMO pressure sensor for a one-sided, 6 m high concrete pour on the south-eastern abutment wall. Due to the required surface finish, no through sleepers could be used, which added to the challenge. The use of the pressure sensors helped to precisely determine the optimal concreting speed and to prevent overloading of the formwork, thus increasing safety.
