Hitting the heights in Kuala Lumpur
Kuala Lumpur - Malaysia
Approved on 30 January 2013 by the Prime Minister of Malaysia, this ambitious, high prestige construction project has been growing steadily upwards and is due to be completed this year. The Four Seasons Place Kuala Lumpur will then move into second place among the world's tallest hotels.
Located next to the iconic Petronas Towers, the 343-metre-high skyscraper will contain 77 floors housing 242 Four Seasons private residences and 27 apartments. In addition, the building will feature a Four Seasons hotel with 209 rooms, a five-storey, 27,900-square-metre luxury shopping centre and a multi-storey car park.
Top performance under tropical conditions
Meinhardt Malaysia, the planning office entrusted with the mammoth project, opted for MC and the concrete additive Centrilit Fume SX as a result of MC’s work with ready-mix-concrete manufacturer CEMEX Malaysia to develop a viable formulation for the specified high-strength concrete.
The tropical climate makes manufacturing such a concrete extremely challenging. The high air humidity and occasionally extreme outdoor temperatures makes comprehensive quality assurance essential, something which CEMEX Malaysia and MC were able to ensure. It is also the first high-rise building project in Kuala Lumpur to require such a high concrete strength value of 80 N/mm² for the mega columns and load-bearing walls. Despite the incredible ambient heat, which aver-aged 30°C even at night-time, it was necessary to maintain a maximum core temperature of 70°C in the poured concrete.
The stuff of which special concrete is made
Using Centrilit Fume SX made it possible to reduce the cement content in the concrete, keeping hydration heat generation within reasonable limits. As a suspension, Centrilit Fume SX can be added more efficiently and ensures less concrete stickiness compared to a powder. During hydration, Centrilit Fume SX reacts with the free lime of the cement to form calcium hydrosilicate, thus ensuring the development of a high-density concrete. As well as increasing the strength of the material and its resistance to corrosion, the slurry-like additive also improves the structural cohesion of the fresh concrete so that it can be pumped and poured with ease. Thanks to committed technical collaboration by all involved, the resulting concrete was ideal for such a challenging job, improving the efficiency of the build and yielding tangible economic benefits for the investors. As a result, the Four Seasons Place Kuala Lumpur will now be open for business within the current year.
