# [The New Henninger Tower – with MasterGlenium ACE and MasterSure](https://blog.master-builders-solutions.com/en/the-new-henniger-tower)

Almost 60 years ago, the recently constructed [Henninger-Turm](https://de.wikipedia.org/wiki/Henninger-Turm) (Henninger Tower) – the grain storage silo of a brewery in the Sachsenhausen district of Frankfurt – became a major landmark and a symbol of Frankfurt almost overnight. It was to be replaced by a new tower which was to house flats and offices instead of gain, at the same time as maintaining its function as a symbol. The concrete for the new building was optimized using concrete admixtures from [Master Builders Solutions](https://www.master-builders-solutions.com/en-gb).

At the end of the 1950s, [Henninger-Bräu AG](https://de.wikipedia.org/wiki/Henninger-Br%C3%A4u) built one of the world’s tallest [grain storage silos](https://de.wikipedia.org/wiki/Silo) in Frankfurt am Main, the Henninger Tower, which soon became a symbol of the banking metropolis on the River Main. Apart from its main function is a storage silo, the building, which was almost 120 metres high, housed a tavern in the lower section and one, later even two rotating restaurants and an observation deck in the barrel-shaped tip of the tower. However, the building was closed to visitors from 2002 onwards for fire safety reasons and the traditional cycle race “Rund um den Henninger-Turm” (around the Henninger Tower) changed its route and its name in 2008.

Demolition work finally started in 2013 and the old building was to make way for a new residential development.

## **New tower in the old shape **

The design by Frankfurt architects Meixner Schlüter Wendt takes up the iconic [shape of the landmark](http://www.meixner-schlueter-wendt.de/index.php?id=367&bigView=1&bigPic=HT_gross_01.jpg): the tower was to accommodate 206 flats and office units and a modern version of the tip, with straight lines, was to house a rotating restaurant and an observation deck with public access. The tower complex, with an overall height of about 140 metres, also includes a U-shaped six-storey building surrounding the bottom of the tower like a courtyard.

The object of the design was to produce a silhouette which was at least similar to the old tower as part of the Frankfurt skyline.

## **Requirements for concrete: flowing properties and consistency extension **

500 cubic metres of high-strength C 80/95 concrete were to be supplied for the project. Despite a low water/cement ratio, the concrete needed to have good flowing properties and to maintain its consistency over a longer period of time. The solution adopted was to combine two concrete admixtures. [MasterGlenium ACE 460](https://www.master-builders-solutions.com/en-gb/products/masterglenium) was added to ensure good flowing properties, combined with [MasterSure 900](https://www.master-builders-solutions.com/en-gb/products/mastersure) as a consistency extender.

MasterGlenium ACE is a superplasticizer based on modified polycarboxylate ether which has a very high superplasticizing effect with low dosage. With its outstanding dispersing effect, this product can be used flexibly and is especially well-suited for the production of high-strength and other special concretes.

[MasterSure 900](https://www.master-builders-solutions.com/en-gb/products/mastersure) is also based on modified polycarboxylate ether: the specific modification allows unprecedented flexibility in extending the consistency of concrete.

## **Combination of flexibility, safety and convenience **

In combination, the two additives allow optimum control of consistency even under difficult conditions. The system, therefore, offers a high degree of flexibility, safety and convenience for ready-mixed concrete producers.

On this project, the addition of MasterSure 900 reduced the consistency loss to five centimetres in an hour. This meant that the high-strength concrete could be delivered to the site without any problems, allowing a generous time window for careful concreting.
