FIELD: binding agents.
SUBSTANCE: invention relates to the field of binding agents, in particular to binders for building products such as concretes and mortars. The binding agent includes at least one raw clay, including at least one clay mineral, and the total content by weight of the clay mineral is from 1% to 60% relative to the weight of the binding agent, at least one limestone or dolomite filler; at least one water-retaining agent; at least one additive selected from flocculants, hydrophobic water repellents, latexes, hydraulic binders, adhesives, and cationic surfactants, provided that when the binder includes a hydraulic binder, the total content by weight of the hydraulic binder is less than the total content by weight of the clay mineral.
EFFECT: improving the technological characteristics of the finished mortar or concrete, such as water resistance and adhesive strength.
