The use of dust wastewater of sawing and sanding of the straightening device and of granite for the production of a cellular structure

摘要

The invention relates to the exploitation of the residual dust 1 - photograph Appendix 1/12 from the cutting and polishing of marble and granite, which is recovered downstream of the benches in the form of sludge 2 - photograph Appendix 2/12, which is used as it is to produce a cellular structure characterised by internal cells 3 - photograph Appendix 3/12, of more or less pronounced density, depending on its density and exhibiting high-performance technical characteristics especially in respect of the thermal conductivity coefficient. Its application in the building industry in particular in the private housing sector covers virtually all of the structural parts of the fabric. IMAGE
