FIELD: construction.SUBSTANCE: wood-cement mix contains as an inorganic additive wastes of mechanical processing of talc chlorite in the form of a powder with particles of size of not more than 500 micrometers, including up to 0.02 wt % of particles with size of up to 0.5 micrometers, including nanoparticles, Portland cement, ground wood, polypropylene fibres, at the following ratio of components, wt %: Portland cement 33-42, sawdust 43-50, talc chlorite 5-6.9, liquid glass 5-7.5, calcium chloride 2.4-5, polypropylene fibres 0.1-0.2. Water is added to the specified mix to produce water-cement ratio of 0.8-1.2.EFFECT: increased strength and ecological compatibility of material from proposed mix.2 tbl |
