FIELD: manufacture of building materials. ^ SUBSTANCE: invention relates to manufacture of dry building mixes and directly concerns use of inorganic materials as aggregates of differing shape and granule size. In a dry building mix including crushed expanded-clay concrete (30-95%) and inorganic aggregate (5-70%), the latter is naturally occurring or synthetic wollastonite crushed to achieve needle-shaped grains. ^ EFFECT: enabled manufacture of building parts and coatings more suitable for exploitation under complicated conditions, in particular owing to elevated bend strength. |
