Using Halan stone as a Preproduction Unloaded Wall Instead of Bricks 120 mm
Al-Ma'mon College Journal,
AbstractTo reduce using the brick as a unloaded walls in frame building by using Halan stone (Limestone) as a natural stone to preproduction walls and is assemble in working area. The suggestive wall is consist from a double stone, the first one (450x1000x100)mm as 2 parts, the second one (150x 1000x50)mm as 2 parts, and arrangement parts by roller bolts as a hollow box used to put insulating materials and covered by decoration plastic hollow sheet to form the external finishing material, and used gypsum 3 mm as the internal finishing material, therefore, the total wall thickness is 157 mm.
The researcher build (1x1x2)m room sample, in third story in building (Baghdad city– Latitude 33.2º North),and (1x2)m testing wall to east orientation, while the other surfaces were insulated by 200 mm styropor sheets and using Air – Conditioner 0.5 ton of refrigeration to afford the standard thermal comfort, and measured the walls & air temperatures for 15 hr/day for summer season (May to September) .
The researcher found that , the suggestive wall saved 63% electrical energy for cooling purpose and also decreasing wall weight by 30% but increasing cost by 20 % when comparison with common brick wall.
