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.

This paper discusses ways of recycling woodworking waste into light aggregate, optimal compositions of modified binders, as well as the mechanism of cement hydration in the presence of dispersion polymer powders. The methods of obtaining light aggregate based on woodworking waste by granulating in a disc granulator, which is a plate with a tilt angle of 450 and a number of turnovers of 17-19 rpm, are considered. Methods for obtaining granulated aggregate using sawdust of various fractions by the roasting free method are presented, optimal granulation modes are determined, and the main characteristics of the resulting aggregate and concrete based on them are studied. The optimal composition of granulated aggregate on modified cement provides 40 … 60 % of wood processing waste, 60 … 40 % of cement, 25 … 32 % of water and granulation time - 7 … 9 minutes. With this composition, the bulk density of the resulting aggregate corresponds to 850…750 kg/m3, the maximum strength of the granules when compressed in the cylinder is 3.5…4.1 MPa. The optimal content of the polymer additive in the binder is in the range of: mowilith - 0.4…0.7 % and tylose - 0.21…0.13 %. Granulated aggregate on modified aggregate has a frost resistance in the range of F35… F50. The choice of granulated aggregate on modified cement showed the effectiveness of the aggregate for light concretes. The strength characteristics of modified concrete of 25-75 brands were studied. The mechanical properties of modified concrete depending on the average density were studied. Concrete with an average density of 1000 kg/m3 has M25 brand, at 1200 kg/m3 - M35, at 1300 kg/m3 - M50, at 1500 kg/m3 - M75.

The manuscript presents the results of analysis and synthesis of researches of scientists of the CIS and Kazakhstan on the use of various clays for the production of wall ceramic products. There was investigated the application of refractory and brown clays, loam to optimize the composition of the furnace charge and the choice of technological parameters of the production of wall ceramic products. The drying and burning properties of the samples burned at 850 °C, 900 °C, 950 °C, 1000 °C and 1050°C, 1100÷1150 °C with determination of strength, shrinkage, water absorption of the material at all specified burning temperatures were studied. The optimal burning temperatures for the study of the burning properties of the above three clays are determined. In many regions of the Republic of Kazakhstan the problem of production of high-quality wall ceramic manufacture is particularly acute. Most seasonal plants turns out low-branded products (the M75-100, B < 25), often not conforming to requirements of normative documents, does not have the expanded range, the decorative brick necessary for construction of low houses (country, cottage buildings) as implementation of the similar program requires, first of all, detailed studying of technological and physical and chemical features of clay raw materials is not issued.
