Identification of the Compositions and Analysis of Changes in the Properties of Lime-Sandy Binders as a Result of Application of Petroleum Bituminous Rocks and Their Processing Waste

In the paper the questions of technology of binding of silicate materials applying petroleum bituminous rocks (PBR) and waste processing, in particular: optimization of ratios of raw components of a mixture of silicate materials, the development of optimal technological parameters of production of silicate materials, technological aspects of production of these materials. The chemical-mineralogical and structural features of PBR and their processing waste are revealed. The optimal compositions of binders were studied using waste from the processing of PBR as an activating component of lime. The optimal ratio of the mixture of waste from the processing of PBR with lime and the technological parameters that allow to ensure the grade of the lime-sand binder from 400 to 500 are established. As a result, technological processes for the production of binders based on PBR and waste from their processing were justified and developed. Silicate materials based on them have high physical and mechanical properties and meet regulatory requirements. The proposed compositions and conditions for the preparation of these binders have high resistance in operating conditions.
