FIELD: construction.
SUBSTANCE: invention is related to composition of modified component of magnesia cement. Modified component of magnesia cement contains active oxide of magnesium and metakaolin - thermally activated kaolin with preferable size of particles of less than 10 mcm, in amount from 2% to 50% of active magnesia oxide mass. Invention is developed in dependable claims of formula.
EFFECT: increased compression strength on magnesia cement in water saturated and dry form, increased sedimentation resistance of concrete mix and mortar, increased water-retaining capacity of magnesia mortars and concretes, increased adhesion strength, resistance to blooming.
