Concrete with biomass bottom ash - Waste materials replacing scarce resources

Faglige nøgleord: Concrete, sand, natural resources, energy, production

Oplæg tilgængeligt på: Dansk og engelsk

In my presentation I will of course talk about my project, but also how I ended up at DTU, what I do on a daily basis, both as an engineer and a researcher. I have experience from university, but also working in the construction industry in Denmark. 
Project description
I work with replacing natural sand in concrete, since it is a finite resource that we, both in Denmark and globally, are starting to run out of.. The material I am investigating is the bottom ash from biomass (mostly wood) combustion, a type of ash that is currently landfilled or exported to countries with less strict laws regarding waste materials. If this works, power plants 
Sustainability
When less sand resources are available locally, longer transport of sand and gravel is necessary. This leads to higher costs for concrete, and more CO2 emissions affecting all of us
My path to the PhD project
I was born in western Jutland, where I went to Vestjysk Gymnasium Tarm (VGT). After that, a sabbatical year, in which I applied for structural engineering in DTU (bygningsingeniør). I took a bachelors degree, and decided to stay for a masters degree as well. Then, I worked 4 years for a large contractor (entreprenør), before going to a consulting engineer (rådgivende ingeniør) for 2 years. Here, I got the opportunity to do a PhD.
