The Use of Polypropylene fibres in bricks and tiles as a crack-controlling agent


Today polypropylene (PP) fibres are used as a crack-controlling agent in concrete. However, the owner of the company Danish Fibre wants to clarify, whether PP fibres has a similar effect in bricks and tiles. If this is the case the tile and brickworks can reduce their cost of production considerably.   

In order to clarify this, a technical project was initiated, where various fibres were manufactured and added to bricks and tiles during full-scale tests at relevant tile and brickworks. 

Afterwards the manufactured bricks and tiles underwent various technical examinations and tests carried out by Plast Center Danmark and Force Technology

Simultaneously Syddansk Universitet made a market survey in order to estimate the market potentials. The project is still in progress, but very interesting and promising results have been obtained regarding stability of tiles dimensions during drying processes.

Outcome and benefits

The project is still in progress, but so far the participating companies have obtained major technical input regarding the addition of fibres to bricks and tiles. Moreover, they have obtained valid and statistical significant information about their own production, as all testing has been carried out by the use of statistical planning tools. 

Through the project work the partners have also increased their network and new collaborations have been established. 

Production Manager at Danish Fibre, Palle Kuntz says: 

- For some years we had considered initiating this project, but could not do so due to lack of finance. However, due to the assistance and project management by the cluster, the project was initiated in 2009.
