AbstractAbout the AuthorReferences
Advantages of composites on the basis of mineral binders and an organic filler from the waste of logging, lumbering, and machining are shown. Negative qualities of a wood filler which make it difficult to obtain material of high strength are determined. Organo-mineral concretes for wall structures, in which the waste of wood machining – sawdust and bark – are used as a light filler, and slag- and ash-alkaline binders consisting of ash-slag wastes and liquid glass from micro-silica serve as mineral binders, are proposed. Quite high physical-mechani- cal characteristics of such concretes due to the phase composition of the binders used and the peculiarities of liquid glass are explained. Processes and phenomena, which take place when forming the contact zone of wood filler – binder, have being studied. It is concluded that concretes obtained on the basis of waste of larch machining and slag- and ash-alkaline binders on the liquid glass from micro-silica meet all the requirements for enclosing structures. The possibility of using the bark, as a filler, is shown. It is noted that for the successful use of bark , the simultaneous use of low- and high-module liquid glass is needed. For regions where metallurgic slag and furnace bottom ash from coal burning are absent, it is pro- posed to use the peat ash for organo-mineral concretes.
