Estudo da potencialidade do resíduo cerâmico incorporado na produção de tijolos maciços de solo-aglomerante(s)

Abstract

The supply chain of the construction industry stands out as a source generating of significant amount of solid waste in urban areas, the so-called waste, construction and demolition, which cause enormous environmental impacts and disturbances in the road systems and networks collecting drainage and sewage from the cities. An alternative to minimize the effects of deposition of these tailings is the reuse thereof as material for the manufacture of other products. An alternative to minimize the effects of deposition of these tailings is the reuse thereof as material for the manufacture of other products. In this context, the incorporation of grog, arising from breach of the ceramic block applied in the execution of the masonry seal, to produce solid bricks of soil-binding agent (s) is possible due to the pozzolanic presents the ceramic waste when subjected to process grinding to increase the surface area of its particles. This scientific study aimed to evaluate the physical, mineralogical and mechanical properties of solid bricks produced from ternary formulations of soil-lime-ceramic waste, soil-cement-ceramic waste and quaternary soil-cement-lime and ceramic waste. In the development of research was performed the physical , chemical and mineralogical characterize of materials applied and bodies of the test piece cylindrical was molded with the addition of 2% and 4% residual ceramic compositions in the soil-binder (s), the contents 8%, 10% and 12%, which were cured and subjected to testing of compressive strength, water absorption and durability modified. With the most significant results obtained in the experiments were made of solid bricks soil-binder (s) and ceramic waste, the levels cited above, which underwent the same sequence of tests performed on the body-of-proof cylinder, whereupon samples sent for testing X-ray diffraction and scanning electron microscopy. Experimental results verified that in terms of compressive strength, water absorption and durability modified ternary composition soil, 12% cement and 4% ceramic waste showed more significant values. In quaternary mixtures, formulation soil, cement 10%, lime 2% and 2% ceramic waste performed better.
