Strategic projects: A holistic approach to achieve the national gravel goal

Important results from the project

1 Characterization Methods for fine-grained ballast Many methods both in literature and in earlier projects have been studied. Although methods suitable for development of fine grained aggregates. 2 modeling program that values the crushed rock in concrete There are many theories and models of how to proportion concrete. The information and theories have been collected in a program indicative visarpå how it should work. 3 Dissemination of knowledge and competence building We have reached 300personer in the aggregate industry and textfor Concrete Handbook, Ballast and mixdesign.

Expected long term effects

The results have been disseminated and tested at the transition from natural materials to krossmateril. Because less gravel used will also need a good knowledge steadily increasing to ensure the sustainable production of crushed rock. For concrete producers will knowledge be woven into The Concrete handbook is an important tool industry

Approach and implementation

The project was implemented with literature studies and experience gathering initially and has since evolved into more practical rheological investigations and the creation of algorithms that can be used in the software is a key objective. This approach will also indicate how production is affected in terms of quantity of additives
