Purpose and goal

This project aims to find the best possible way to use natural Swedish clays as a clinker replacement in cement and concrete. The overall goal of the project is to activate found clays in ordert to be used as a clinker replacement in cement and concrete and by this drastically reduce greenhouse gas emissions and environmental impact when constructing infrastructure buildings made from concrete.

Expected results and effects

The substitution of fraction of cement clinker with calcined clays will highly effect the reduction of the emission of greenhouse gases due to cement production and therefore decrease the environmental impact of the production of concrete used for infrastructure buildings. Moreover, a better use of the available Swedish Resources will be achieved.

Planned approach and implementation

In order to account for the potentials of the use of Swedish clay resources, a three-step project is suggested. Step I will focus on optimizing the activation process of the different clays. In step II, the reactivity and pozzolanic activity of the clays in cement systems will be studied. Finally, step III, the possibility of application of activated clay in existing Concretes used for infrastructures will be investigated.
