Abstract The paper deals with the issues of technology of binding silicate materials with the use of mineral waste from the processing of petroleum bituminous rocks (PBR) – optimization of the ratio of raw components of the mixture of binders, development of optimal technological parameters for their production. The optimal compositions of binders were studied using waste from the processing of PBR as an activating component of cement. The influence of mechanic and chemical activation on the change in the acid-base parameters of the suspension from the crushed material was revealed. The effect of the content of additives on the degree of hydration was studied. The influence of the hardening conditions on the strength of the binder with additives of waste from the processing of PBR was studied. As a result of the experimental work carried out, technological processes for the production of binders based on waste from the processing of PBR were justified and developed. The optimal ratio of the mixture of waste from the processing of PBR with cement and the technological parameters that allow ensuring the optimal grade of the cement-sand binder are found. Silicate materials based on it have high physical and mechanical properties, meet regulatory requirements and have high resistance under operating conditions.
