Among the researches applied to the sustainable production of construction materials there are the incorporation of rejects from the civil construction to clayey masses to make bricks, tiles and other products of structural ceramics. Main objective of this paper is to show the results of these mixtures. Spherical samples had been conformed incorporating 1%, 5%, 10%, 20% and 30% of reject from the civil construction in mass. These samples had been evaluated on compressive strength after dried to 110°C and to color and compressive strength after burns to 950°C. The composition that presented better results had been conformed by extrusion in prismatic samples. Then, the dried to 110°C and burnt to 950°C samples had been evaluated on flexion strength and in linear retraction too. Industrial test was made having produced 1500 ceramic blocks that show similar or better properties of blocks without incorporation. It was measured the ceramic and leaching properties of the blocks. The mixture with 5% of rejects in the clayey mass show the better results in all tests.

A procedure that comes being studied for the exploitation of powder waste rejected from the sanitary ware production is the incorporation in mass for red ceramics. Objective of this work is to present the results gotten in the incorporation of this rejects. The used clay was from ceramics industries of the Jundiai region, SP. Spherical bodies test samples had been conformed incorporating 1%, 5%, 10%, 20% and 30% of the powder waste in mass. These bodies had been evaluated on compression resistance after dried to 110°C and to color after burns to 950°C. The composition that presented better results had been conformed by extrusion in prismatic bodies test samples. Again, the dried to 110°C and burnt to 950°C bodies test samples had been evaluated on flexion resistance but to linear retraction too. It was measured the ceramic properties of the burnt bodies test samples. Results indicate that there is a great potential in the formula with 30% incorporation of powder waste in mass. Comparative assays were made being used a mixture without incorporation of the denominated white reject.

Carbon/mineral complexes are materials with surfaces covered partially or totally by carbon materials contains. They have high industrial potential uses as material adsorbents and ceramic filters. The objective of this work is to evaluate the corrosion strength in acid and alkaline solutions, and the adsorption capacity of methylene blue of some materials prepared in the LMPSol. The compositions were prepared with an industrial common clay named “taguá” and organic and inorganic additives from industrial residues up to 50%. The corrosion test was performed in water at 60°C and in aqueous solutions of HCl and NaOH at room temperature, with mass losses measured after 15 days. The samples were pressed manually and heated at different temperatures: 110°C, 350°C and 500°C. The performed tests were transverse flexural strength, porosity and water absorption.
