Abstract Eucalyptus nitens (E. nitens) has been much used for producing paper but also shows promise for structural applications. In this study, static compressive tests were undertaken to examine its suitability to be used in an innovative composite column. The composite column was comprised of a rectangular steel tube with E. nitens timber infill. The nonlinear compressive behaviour of the composite column filled with E. nitens wood for both dry and wet conditions was examined. The same tests on rectangular steel tubes and bare dry and wet E. nitens samples were also undertaken as a comparison. For samples with different conditions, More > Graphic Abstract

Abstract To solve the problems of high moisture content, high viscosity, and poor engineering mechanical properties of soil, this paper using with steel slag (SS) and desulfurization ash (DS) as initial raw materials, realizing the cooperative treatment of solid waste and solidification of silt soil. The synergistic utilization of SS and DS can reduce the production cost of curing agent and promote its own consumption. According to blended cement of various SS contents and inspected compressive strength performances, the most suitable raw materials ratio was selected. The best formula for this curing agent is cement:steel slag = 3:7… More >
