Assessment of precast cellular lightweight concrete (C. L.C.) support structures

摘要

Traditional materials, used in external supportstructures, like timber and normal concrete have certainfundamental shortcomings. These shortcomings are highlightedin an analysis using defined material and structural properties asthe basis. Cellular lightweight concrete (C.L.C.) has beenidentified as a support material with excellent properties. Thispaper assesses the performance of a modular precast C.L.C.support system specifically developed for deep level seismicallyactive mining. This CLC technology can be engineered to tailorsupport to suit a wide range of mining types.
