Wall Ceramics on the Basis of Low-Grade Alumino-Silicate Raw Materials and Anthropogenic Additives
Currently, much attention is paid to the development of energy saving technologies, expansion of raw materials base of construction ceramics, creation of effective materials, issues of improving the product quality, compliance with environmental standards. The aim of the study is the preparation of ceramic brick on the basis of alumino-silicate raw materials and anthropogenic additives. As additives, drill cuttings and sludge from the station of deferrization are used. The physico-chemical, mineralogical compositions and firing properties of clays and slimes were studied. The content of coarse inclusions and granulometric composition of clayey rocks of the West of Orenburg Region was revealed. The basic properties of ceramics (strength, density, water absorption etc.) in the temperature range 900-1150 °С were determined. The expediency of the use of clay raw materials with addition of corrective additives when producing ceramic bricks was also determined. Implementation of measures of oil production waste treatment is primarily aimed at reducing the negative impact on the environment, and also are important socio-economic benefits for the enterprise: reduction in fees for waste disposal; the profit from the sale of products of disposal. Scientific novelty of the work is the substantiation of the possibility and prospectivity of the use of slime waste as technological additives when producing ceramic bricks. This confirmation is based on the fact that, as a result of high-temperature burning of samples on the basis of alumino-silicate raw materials, a new type of crystalline lattice is formed that contributes to improving the physical-mechanical properties of wall ceramics.
