Hitting the heights in Kuala Lumpur

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.
