Abstract:
Two clay brick samples an old one and a new one were collected in Khartoum, Sudan. The samples were analyzed by x-ray fluorescence to study the constituent element. The specific heat capacity, water absorption, moisture content and thermal mass were measured, then the two samples were coated with a layer of cement and measurements were repeated. The obtained results for the specific heat capacity ranged between 710.6JKg-1K-1 and 930JKg-1K-1 for the water absorption they ranged between 6.05% and 9.9%, for the volumetric heat capacity they ranged between 0.94 × 106 Jm-3K-1 and 2.74 × 106 Jm-3K-1 while for the moisture content at 4000C they ranged between 0.19% and 0.03%.
