Runway reconstruction Sabiha Gökçen Airport (SAW), 2018

2019-07-02T13:52:30+01:00

Initial situation Istanbul-Sabiha Gökçen Airport (SAW) is Istanbul's second major airport and handles over 900 aircraft movements each day and 31.4 million passengers annually (2017) with just a single runway. Due to the success of the airport and its steadily increasing traffic over recent decades the runway was in poor condition. Especially, the center portion in the touchdown areas showed substantial surface damages and was in need of renewal. However, construction on this intensively used air traffic surface is only possible during the night when operations are halted. Solution and assessment From March to September 2018, a total of [...]

Repair of taxiways with a slipform paver 2015, Vienna Airport (632)

2019-06-14T09:53:32+01:00

Initial situation In the parking areas at Vienna Airport the concrete paving had to be replaced on a surface with a width of approximately 7m and a length of approximately 30m. As the area was an important intersection, the closure periods had to be kept to a minimum. To carry out the construction process as quickly as possible the concrete was installed using a slipform paver. Solution and assessment For this project the rapid-hardening concrete Concretum® Q-FLASH 2/20 was used. It reaches a compressive strength of approximately 20 N/mm2 just 2 hours after the start of mixing. As the open [...]

Repair of runway 10/28 ZRH, 2015 (888)

2019-06-14T09:53:33+01:00

Initial situation The section on runway 10/28 at Zürich Airport had several damaged slabs with an area of between 20 m2 and 90 m2. On account of the narrow repair window, it was important for concreting works to take place during the night. In a timeframe of approximately seven to eight hours, the concrete slabs were broken with heavy machinery and then reinforced and poured with rapid-hardening concrete. The objective was to be able to resume flights at the latest by 5:30am. Solution and assessment In this project, the rapid-hardening concrete, Concretum® Q-FLASH 2/20, was used which reaches a [...]

Repair works on runways and taxiways at Budapest Airport 2014, Hungary (822)

2019-06-14T09:53:34+01:00

  Initial situation With recurring need for repair works at Budapest Airport on takeoff and landing runways, as well as taxiways, repairs were made to various small and partial surfaces on existing concrete slabs. Solution and assessment The individual repair areas reported varying volumes, ranging from approximately 40 to a maximum of 850 litres. To address this situation, the rapid-hardening drymix mortar Concretum® Q-REP G was used for smaller places, up to a maximum excavated volume of 200 litres, whilst for all larger excavated volumes, rapid-hardening concrete Concretum® Q- FLASH 2/20 was used. The drymix mortar Concretum® Q-REP G [...]

Reconstruction of runway, Zurich Airport (416)

2019-06-14T09:53:34+01:00

Initial situation As part of the runway renovations at Zurich Airport, concrete slabs with a total volume of 1,500 m3 were replaced. Conventionally, air operations would have had to be suspended for a substantially longer period because of the numerous operational and safety requirements. To minimise disruption, over the past 10 years, the relevant operational transport surfaces at Zürich Airport have been reconstructed using rapid-hardening concrete. Runway reconstruction took place in the summer and autumn months with fresh concrete temperatures from 18 °C to 33 °C and above. To ensure flexibility and not to hinder work on other parts [...]

Reconstruction of the Zürich Airport Runway (248)

2019-06-14T09:53:34+01:00

Initial situation At Zurich airport, several concrete slabs in the runways were heavily damaged and had to be reconstructed. High traffic volume during the day, constrained this reconstruction work to a very short overnight time window. Solution and assessment The rapid-hardening concrete Concretum® Q-FLASH 2/20 reaches a compressive strength of approx. 20 N/mm2 just 2 hours after adding water and despite this speed, remains workable for approx. 60 minutes. In addition, Concretum® Q-FLASH 2/20 has low shrinkage. As a result, the slabs do not bow and the risk of cracking is considerably reduced. This guarantees a long lifespan for [...]
