Norrland Eco-Concrete - Using wood production ash for ecological concrete
Published: 18 February 2022
In this project, we aim to reduce the use of cement by using wood ash in ecological concrete for lower carbon dioxide emission.
Concrete is the most widely used building material because it is inexpensive and has clearly predictable properties. One problem with concrete is carbon dioxide emissions during cement production.
This project aims to use waste wood ash to replace some cement in the concrete. As the pozzolanic properties of the wood ash vary, a new process technology will be developed that improves the pozzolanic properties of the ash, so that wood ashes from different sources can be used as quality-assured cement replacement.
