Abstract
This article addresses experiments and theories of a novel self-compacting gypsum
based light-weight composite (SGLC), wherein -hemihydrate was used as binder and
one light-weight material (0-2 mm) was used as aggregates. The mix of the new
composite was designed based on packing theory applying the modified Andreasen and
Andersen (A&A) grading line to achieve an optimal packing of all the applied solid
materials. The effect of the distribution modulus (q) in the Andreasen and Andersen
equation was investigated. The developed mix was studied from its both fresh and
hardened state, including the flowability, density (porosity), and mechanical properties.
The thermal physical properties of the new developed composite were investigated too.
The study demonstrates a considerable improvement of the new composite from both
thermal and mechanical properties compared to normal gypsum plasterboard.
