Abstract: Taiyuan is a city with more moutains, less loess resource and abundant coal gangue. This paper studied the feasibility of turning coal gangue into filling in Taiyuan region, based on successful experience home and abroad. A series of tests on physical-chemistry properties and mechanical characteristics of the coal gangue proved that coal gangue used in the experiment has good chemical properties, grain composition. The coal gangue is a kind of non-sticky coarse grained soils which can drain off water freely, and it can be used as the filling of foundation. Based on tests, this article provided a theoretical basis and a favorable reference for engineering application of coal gangue and its research and development in other areas.

Abstract: The clods of dirt are filled within reinforced concrete frame space, which composes raw soil composite wall. This structure has the advantages of lightweight, high strength, ecological and energy-saving and so on. In order to study the key building technology of raw soil composite wall’s structure, this paper analyzes and investigates from the structural materials, wall production and its connecting structure method, and has produced raw soil composite wall structure’s construction technology and relevant quality requirement, which provides the reference for the engineering application about the raw soil composite wall.
