The massive growth of the ceramic industry and the consequent demand for construction materials worldwide has motivated the search for alternative solutions aimed at reducing the use of mineral / natural resources as the main source of raw materials. One of the strategies frequently adopted by the scientific community is the reuse of industrial waste. It is beneficial not only to reduce the overexploitation of mineral resources but also to reduce the environmental, economic and social impacts resulting from their incorrect disposal/treatment and consequent deposition on land unsuitable or that purpose. Duetoconsiderationssuchasphysico-mechanical characteristics and the high production rate, two different types of industrial waste were selected for this work, ashes resulting from the burning of coal in thermoelectric power plant, commonly known as bottom ash (B), and the Marble Powder (MP). It was intended to test the technological feasibility of the manufacture of ceramic materials produced from clay mixtures containing these two residues. For this purpose, the fine fraction(<63μm)obtained from the sieving of the marbleresidue(MR)and slag(Bf)was used,aswellasacoarsergrainslagfractionrangingfrom63-125μm(Bg). The resulting test samples were subjected to a firing of 950 °C under an oxidizing atmosphere, following a primary drying process. Faced with the standard values, the new ceramic materials obtained from MP have seen their mechanical and porous characteristics decrease and increase, respectively. Atthesametime,althoughtheadditionofBinno way influenced the mechanical characteristics,a significant improvement the porous characteristic was observed. The incorporation of these residues produced a color very close to the original sample material. Keywords: industrial waste, ceramic, construction materials, bottom ash, Marble Powder

In recent years the production of products derived from wood and bamboo are increasing, due to the search for a more rational exploitation of these raw materials. Amongst these products, the particleboards production combine sustainability and rationality in the use of these materials. In this context, this work has the objective to study the application of alternative raw materials in the manufacture of Medium Density Particleboards (MDP), using residues from industrial processimg of coffee and bamboo. MDP had been produced with particles of giganteus bamboo of the Dendrocalamus species and particle of coffee rind in the intermediate layer of the particleboard, bonded with polyurethane resin based on castor oil. The physical and mechanical characterization was carried out accordingly to NBR 14810-3 (2006). The physical properties evaluated were: of water absorption for 2h and 24h; thickness swallowing for 2h and 24h; density, humidity content. The mechanical properties evaluated were: Tensile strength, static bending (MOR and MOE). The results were compared with NBR 14810-2 (2006) and also with the ANSI A208-1 (1993). The physical performance of these particleboards was below the values recommend by the Brazilian norm. Also the mechanical characteristics are not improve, demonstrating that the inclusion of coffee rind did not benefit the physical characteristics and nor the mechanical ones. However it can be used as construction materials for partitions and ceiling panels.

Abstract: The presented study mainly focused on investigating detailed engineering properties of municipal solid waste incineration residues as road construction materials with different application classes. Also, the leachability of heavy metals and salts in the residues as a function of the ratio of liquid and solid was tested. The Chinese specifications about road construction materials were employed to evaluate the application capacity of the waste incineration residues. The obtained results indicate that bottom ash basically complies with the technical requirements for road base and sub-base materials with exception of the low compataclity and high organic content of the fine fraction. The toxicity test showed that bottom ash can satisfy the limit values of heavy metals and salts that was established by Chinese specification for hazard solid waste. For the application of the ash in road base, it should be mixed with other materials to improve the compataclity. Pretreatment of fine fraction of bottom ash to remove organic matter is necessary.

This work evaluates the incorporation of solid industrial waste such as rice husk ash, bottom ash from mineral coal and ash coming from the washing of sheep wool in Red Ceramic Mass (MRC) composed of clay. These raw materials were collected from industries in the municipality of Bagé-RS, Brazil. Percentages of 0, 5, 10, 20 and 30% of these wastes were added to (MRC) in order to reduce the environmental impacts, both by the clay extraction as well as for waste disposal. The physical tests (Atterberg limits) made with the clay, follow a normative standard. However, the tests made in the formulations served to compare the formulations’ behavior in relation to the clay. In order to verify if the tests proposed in (MRC) and if the formulations have changed significantly the investigated indexes, an Analysis of Variance (ANOVA) was performed. The results generally indicate that there are statistically significant differences, mainly regarding the Plasticity Index (PI) and the Liquidity Limit (LL), as ash was added in the formulations.

Abstract. To overcome the shortage of natural resources for the production of concrete, many waste materials are used to replace the raw materials of concrete. In this way, bottom ash is one of the major industrial wastes which shall be used as the replacement of materials in concrete production. It shall be used to replace the materials either up to one-third. This review brings out the evaluation of the industrial waste material which can be repeatedly used as a substitution for concrete as fine aggregate. This paper reviewed the use of industrial waste i.e., bottom ash as fine aggregate in the concrete. The parameters discussed were physical, chemical, fresh, and hardened properties of the concrete with partial replacement of bottom ash. By reviewing some of the research papers, concluded that 10-15% replacement of fine aggregates is acceptable for all the properties of concrete. High utilization of natural sources -gives the pathway to produce more industrial wastes which are responsible for the development of new sustainable development.

Lca Methodology

The construction industry is increasingly concerned with improving the social, economic, and environmental indicators of sustainability. More than ever, the growing demand for construction materials reflects increased consumption of raw materials and energy, particularly during the phases of extraction, processing, and transportation of materials. This work aims to help decision-makers and to promote life cycle thinking in the construction industry. For this purpose, the life cycle assessment (LCA) methodology was chosen to analyze the environmental impacts of building materials used in the construction of a residence project in São Gonçalo, Rio de Janeiro, Brazil. The LCA methodology, based on ISO 14040 and ISO 14044 guidelines, is applied with available databases and the SimaPro program. As a result, this work shows that there is a substantial waste of nonrenewable energy, increasing global warming and harm to human health in this type of construction. This study also points out that, for this type of Brazilian construction, ceramic materials account for a high percentage of the mass of a total building and are thus responsible for the majority of environmental impacts.

The aim of the study. Using the latest data of Geoinform of Ukraine, to carry out economic and geographical zoning of the territory of Podillya by mineral resources in order to identify spatial and temporal and dynamic patterns of concentration of mineral deposits, their place and role in the economic complex of the region, substantiation of proposals for optimization of its structure and optimization. Research results. Within the Podilskyi macrodistrict, six mineral-raw areas were distinguished: Vinnytsia, Khmelnytskyi, Tovtry, Chortkiv, Western and Podnistrovskyі. All districts (except Chortkiv and Podnistrovskyi) are of a complex type, that is, mineral resources are concentrated within their limits in the form of macrobunches, deposits, separate deposits. In particular, it is established that the main components of the component structure of mineral resources of Podillya are different types of construction materials. Agrochemical and technological raw materials are of subordinate importance. The isolated mineral resources are characterized by a well-defined set of major and specific (area-specific) mineral resources and a distinct genetic link between the latter and the individual stratigraphic and structural-geomorphological taxones of the territory. Most territorial structures of the region's mineral resources are complex and only a few are classified as grouped. Within the region, multicomponent concentrations of mineral deposits and deposits dominate, in which raw materials for the construction industry most often play a dominant role.On the basis of the explored deposits of solid mineral resources of the region, several mineral-oriented mining hubs were formed and are functioning: Shepetivka-Polonne, Glukhiv-Turbiv, Slavuta and Kamianets-Podilskyi - Chemerivtsi. The fields of medicinal and medical-table waters of Podillya are basic for the formation in the region of territorial and recreational complexes: Konopkiv, Sataniv-Makiv and Khmilnyk. Scientific novelty. Own interpretation of such territorial structural unit of mineral resources as an area is given, regionalization of Podillya territory by combinations of mineral resources is carried out for the first time, the set of basic and specific (peculiar to this area only) types of mineral raw materials and a distinct genetic link of the latter with separate stratigraphs are established - geomorphological taxons of the territory, which are separately formed on the basis of combinations of mineral resources, mining sites and their specificasy was outlined. Practical importance. Economic and geographical zoning of the Podillya area by mineral resources is conducted which will help to form a reliable, holistic view of the actual resource potential of the region and to plan and conduct on this basis by local administrative bodies aimed at optimizing the structure of the present mineral resources and raw materials.

Trends in housing development should be based on the geographical location and climatic conditions of the region, national characteristics and culture, natural resources, transport links, density and living standards. Construction significantly affects the socio-economic development of the region. In this regard, increasing the sustainability of the regional construction complex, which is based on the building materials industry and the construction industry is a relevant and promising area of research.Demand in the building materials market continues to stimulate increased interest in the development of new types of efficient and inexpensive building materials. Since construction is one of the most material-intensive sectors of the economy, which consumes a large number of construction materials and products, various measures are taken to reduce their cost.In this regard, recently in the construction seek to make greater use of local building materials. This allows you to unload transport from long-distance transportation and significantly reduces the cost of construction. However, the building materials industry cannot develop by focusing only on natural sources of raw materials, as the costs of their extraction and processing are constantly growing. The use of man-made waste provides production with a rich source of cheap and often already prepared raw materials, which reduces the cost of manufacturing building materials.One of the promising areas in the construction of affordable housing is the maximum use of building materials and products that can be obtained from local raw materials and industrial waste. As local building materials are offered: clay, sand, soil, straw, reeds, flax. The use of industrial waste solves both environmental, fuel and energy problems and expands the raw material base of building materials.
