This paper presents an experimental investigation of the mechanochemical activation the low-clinker binder production systems on the basis of CaO and Ca(OH)2. It is shown that the effects of the mechanochemical interactions of the investigated components of low-clinked binders with the superplasticizer C-3 do not show a significant effect on the binders’- properties. The main influence is observed in the interaction of Portland cement and superplasticizer C-3. This study aimed to optimize the technological parameters of low-clinker binders’ production using different by-products. The expected economic effects of low - clinked binders is associated with the reduced amount of the clinker as one of the expensive components. Taking into account the cost of using the superplasticizer C-3 and various technological wastes the economic impact is expected to be 20-25% decrease of the total cost in the concrete production.
