Abstract: |
Affordable, sustainable housing plays an essential role in providing equal opportunity for individuals within most communities in the United States, (e.g., in the area of eastern Washington State). In particular, a lack of family residences presents a challenge for the City of Spokane, and low-income residents. Moreover, building materials reuse is an important sustainability issue and concrete waste from demolition of residential buildings presents a challenge. This paper presents preliminary results for development of rubblized concrete foundations. Initial tests were conducted on scaled pseudo-soil/concrete materials to observe the relative stiffness of the proposed system for potential use in planning subsequent phases of testing, including full-scale testing. Initial results of this early testing confirms that a reinforced rubblized footing will likely have an overall stiffness (in terms of response to loading) that is measurably less than that of a conventional reinforced concrete footing. |
