Clinker Silo 60.000 tn, Post-Tensioned, AGET Heracles Volos Plant

Clinker Silo 60.000 tn, Post-Tensioned, AGET Heracles Volos Plant

The Project

Clinker silo at the Heracles plant in Volos, Lafarge Group, made of post tensioned concrete. It is the largest silo of this kind in the Balkans with a capacity of 60,000 tons of clinker, its diameter is 38 meters and its total height is 45 meters, the thickness of the cylindrical shell is only 40 cm and is post tensioned with four anchoring points of tendons on the circumference.

 

The roof consists of a truncated cone composite shell, made of reinforced concrete and steel and was produced using the free cantilever method. This dispenses with the inner framework at this high altitude. The foundation of the silo was made due to the inclination of the rocky substrata with piles of different lengths. The cylindrical shell was made by slip forming.

 

The construction lasted only four months and then the conveying lines were built to connect the silo to the factory. Special attention was paid to the quality of the concrete and the post tensioning, in order to reduce the cracking due to the large temperature differences between clinker and the environment.
