Abstract [en]

Thepurpose of this study is to highlight the possibility of a better workingenvironment through an increased use of Self-Compacting Concrete (SCC). Suchconcrete is denser and more durable, has higher compressive strength and abetter filling capacity. The main advantage of SCC is that it doesn’t requirevibration for proper compaction and therefore is better to work with. Despiteinitial higher cost to order, it becomes cheaper in a life cycle analysis. Ofall industries, the construction industry has the highest number of workersaffected by vibrations. According to statistics 2016, vibration damage totaled 36% of all approved occupational diseases. The resulting damage can rarely becured and often leads to reduced working capacity and to severe life-longproblems. A study showed that exposure increase of vibrations of just 1 m/s2increases the risk of white fingers (9%), Raynaud’s phenomenon (6.9%),neurosensory injury (7.4%) and carpal tunnel syndrome (2.9%). Most of thevarious activities with elements of vibration on the construction site, such assawing, grinding, screwing with machine etc., are difficult to replace withvibration-free methods. But for concrete casting, it is now possible to almostcompletely exclude vibrations by using SCC. The increased knowledge of theimportance of a healthy workplace for the economic performance of constructioncompanies has played a key role for work environment work. One study comparedthe benefits of accident prevention initiatives with the costs of the same. Itwas revealed that the benefit surpasses the costs with the relationship 3:1. Improvementsfor a healthier workplace can be achieved by: New innovations, both mechanicaland material innovations, making work easier. Studies using modern portablesensors from which information can play an important role in the possibility ofreducing work-related musculoskeletal disorders.

Encouragingworkers to use wearable sensors that can alert when ergonomically dangerousmovements are carried out. Changing of an often reluctant culture at theworkplace. Better risk assessment at the design stage. Better planning inproject design in the early stages using new digital tools such as BIM. Betterinformation about risks and safety in order to affect the safety behaviour ofworkers. We recommend a larger working environment study that will show how apositive workplace development with SCC is possible and how much can be savedin this way. Here, medical expertise must be involved to increase reliability.In addition, there is a desire in medical research, on the working environmentand on vibration-related injuries, to fill in the gaps in previous researchthat remain, such as how cold weather and individual risk factors, such assmoking, affect the risk of vibration-related work injuries.  Improved working environment is the mainreason for increased use of SCC. Increased use should provide a moresustainable society.
