KL 118 Tower (C105), Kuala Lumpur

JTK Consult (JTK) was engaged by PNB/Turners International to provide specialist concrete technology support during the design phase of the project. The KL 118 Project is a mixed development located adjacent to Merdeka Stadium in Kuala Lumpur. The structure consists of a commercial area, offices and a residential tower. It will be the highest building in Malaysia >500 m when completed in 2020.

The contractor for the project proposed an alternative design by changing the original C80 for the vertical element to C105 concrete. The initial design mix was proposed by the contractor and JTK agreed a test programme to evaluate the performance of the concrete in terms of workability, strength and modulus. This included the use of basalt aggregates so that the E-modulus limits can be achieved with an adequate margin and consistency.

As part of a concrete test programme various lab trials, plant trials and full scale mock-up columns were undertaken to understand the in-situ concrete properties, and impact of temperature variations. Additional, long term Creep and Shrinkage testing for C105 concrete was initiated to validate the models developed to predict the strength and e-modulus development.

Trial mixes and full scale pumping tests were undertaken for all the proposed high performance concrete mixes including the C105 concrete to confirm that the pumping requirements could be met for the project.
