N2 - The work presented in this paper is part of a larger project investigating methods of reducing
environmental impact, and improving performance, of fired clay brick masonry
walls. Brick masonry has been combined with natural, sustainable materials in order to
create a construction system that is structurally and thermally efficient. This is being accomplished
through a programme of desk based research and physical testing on both
small and full scale samples. The sustainable materials chosen for use in the project are
unfired clay bricks and hemp-lime.
The paper presents initial results from an on-going experimental programme investigating
performance of novel hemp-lime and brickwork composite walls. Hemp-lime provides
sufficient thermal resistance to act as the insulative material in a wall construction. Due
to its low structural strength and stiffness it has not been used in structural applications
to date. Results from preliminary testing suggest that combining structural brickwork with
a hemp lime inner leaf can result in some structural benefits despite its low strength. This
hypothesis has been investigated further at a larger scale. Results of these initial tests
are presented.
