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

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.

Material consumption of production of building materials is determined by the amount of raw materials used for their production, to the total output. One of the ways to reduce material consumption is the use of industrial waste as the main raw material for the production of new construction products. Most of the waste generated as a result of the activities of enterprises are man-made raw materials for the production of products such as brick, lime, cement, etc.Given that man-made raw materials are similar to the natural composition and physical properties and even has a number of advantages (heat treatment, increased dispersion, etc.), the manufacture of building materials from it is usually profitable and justified [4, 5].

Dicalcium silicate (Ca2SiO4) is a major component of Portland cement. It has also been investigated as a potential transformation toughener alternative to zirconia. It has five polymorphs: α, α'H, α'L, β and γ. Of interest is the β-to-γ transformation on cooling at about 490°C. This transformation, accompanied by a 12% volume increase and a 4.6° unit cell shape change, is analogous to the tetragonal-to-monoclinic transformation in zirconia. Due to the processing methods used, previous studies into the particle size effect were limited by a wide range of particle size distribution. In an attempt to obtain a more uniform size, a fast quench rate involving a laser-melting/roller-quenching technique was investigated.The laser-melting/roller-quenching experiment used precompacted bars of stoichiometric γ-Ca2SiO4 powder, which were synthesized from AR grade CaCO3 and SiO2xH2O. The raw materials were mixed by conventional ceramic processing techniques, and sintered at 1450°C. The dusted γ-Ca2SiO4 powder was uniaxially pressed into 0.4 cm x 0.4 cm x 4 cm bars under 34 MPa and cold isostatically pressed under 172 MPa. The γ-Ca2SiO4 bars were melted by a 10 KW-CO2 laser.
