| Popis: | 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. |
