Process for the treatment of wood chippings to be used as a filler for concrete.

摘要

The process for the treatment of wood in the form of particles intended to be incorporated as a filler in concrete consists in drying the wood until a residual moisture content of the order of 10 to 15%, corresponding to the content due to natural drying and in balance with wood under shelter, is achieved, in coating the particles thus dried with pyrogenic silica and in fixing this pyrogenic silica on the wood by spraying a sodium silicate solution.
