Incorporation of Civil Construction Rejects Materials in Structural Ceramic

Abstract:

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.
