The Study on Low Power Consumption Technology of the Walls Based on Powdered Caol Ash and Karst Slab Building Material — Take for Example Karst Region in Guizhou, China

Abstract:

Guizhou is situated in the biggest continuous karst strap. Carbonate rock cropping-out reaches 130,000 square kilometers. It is also a province quite rich in coal resources. There have been constructed 12 thermal power plants fueled with coal. As the inevitable outcome, the discharge of coal ashes each year reaches over 1,580,000 tons. Based on this special material produced by the natural environment, this study designs a kind of powdered-coal-ash building block walls, which not only preserve heat and insulate heat, but also embody the regional features, thus making the powdered coal ash and karst rock become the real green material. With the respect to the designing method, we produce, in accordance with the (JGJ134-2001) standard , a kind of sandwich building blocks, which can retain heat and insulate heat. Then on the block outside, we hang stone slabs to make the slab and the block form a certain width ventilation space, thus a sandwiching wall of powdered coal ash and slab is constructed. By making use of heat pressure principle, heat is discharged. Through theoretical analysis, and simulations, etc., it shows that karst rock material and the powdered coal ash are green materials, which play a necessary part of regional features, heat preservation and heat insulation.
