Environmental Simulation Test Technology of Modern Concrete Structures

In order to study durability, crack controlling of concrete structu res and characteristics of concrete at early age in simulated environment, envir onmental simulation test technology is discussed. This paper describes the succe ssful applications of environmental simulation technique in some fields. The key techniques of environmental test of concrete structures are analyzed. The basic scheme is put forward to construct artificial climatic environmental laboratory with autocontrol and multifunction. Then the layout, function and performance o f the lab is determined suitably. Finally, the equipments and instruments of the lab are discussed. Based on the research, environmental test of concrete durabil ity and crack controlling will be better performed in the future.
