Phòng thí nghiệm quốc gia Sandia, Albuquerque, New Mexico TỔNG QUAN Chương này tập trung vào tài sản vật chất và hành vi cho mũ, tường cắt, và các rào cản phản ứng thấm (PRBS), với một sự nhấn mạnh trên sự hiểu biết cơ chế và các yếu tố ảnh hưởng đến độ bền của họ trong hệ thống quy mô. Thông tin thu được từ thử nghiệm trong phòng thí nghiệm được phân tích trong bối cảnh này. Đọc được gọi là cuốn sách trước trong loạt ngăn chặn, đánh giá của công nghệ Ngăn chặn Barrier (Rumer. | 3 Material Stability and Applications Prepared by Craig H. Benson University of Wisconsin at Madison Madison Wisconsin Stephan F. Dwyer Sandia National Laboratories Albuquerque New Mexico OVERVIEW This chapter focuses on material properties and behavior for caps cutoff walls and permeable reactive barriers PRBs with an emphasis on understanding the mechanisms and factors that affect their durability in full-scale systems. Information obtained from laboratory tests are analyzed in this context. The reader is referred to the preceding book in the containment series Assessment of Barrier Containment Technologies Rumer and Mitchell 1995 as well as Daniel 1993 Gavaskar et al. 1998 LaGrega et al. 2000 Blowes et al. 2000 Naftz et al. 2002 and Reddi and Inyang 2000 for detailed information on the general characteristics of barrier materials mix design approaches and performance issues. In this chapter the emphasis is on fundamental factors and laboratory and field observations that relate to the long-term performance of materials used in constructing various types of containment systems. The overall performance of these systems has been analyzed holistically using the systems approach in Chapter 1. Chapter 2 dealt with models of water and contaminant fate and transport through components of containment systems. It is herein recognized that material properties With contributions by David W.
