FIELD: production of building materials.
SUBSTANCE: invention refers to production of building materials, in particular of mineral bonding substances and can be used in production of lime-slag bonding materials. The bonding material includes blastfurnace granulated slag, a grinding intensifier and calcined soda. As a grinding intensifier it contains dustlike waste of mechanical electrode treatment with the following component ratio, weight %: Blastfurnace granulated slag 92,72-94,90; Dustlike waste of mechanical electrode treatment 0,10-0,28; Synthetic calcined soda 5,00-7,00.
EFFECT: improvement of plasticization, strength and crack resistance.
