Resumo Inglês:

It was investigated the possibility of using recycled paper pulp (old newspapers) and aluminized (long life milk) packaging as additives for red clay in the manufacture of massive ceramic bodies (bricks). Besides the technological aspect, it is of great environmental interest alternatives for the reuse of discarded materials, which are part of the community waste. The paper pulp was obtained from simple aqueous defibration of old newspapers, whereas the packages of long-life milk, because they had plastic layers and stabilized aluminum, were reduced in size and subsequent comminution in micro-mill. The clay for the semi-humid process (with 5% to 10% moisture) was supplied by the adjacent pottery to the UFSM campus. The mass mixing process was entirely manual, using various proportions of clay / paper pulp and clay / aluminized packaging together. The ceramic bodies were also molded manually (metal forms 30x40x60 mm), obtaining a compact mass, apparently homogeneous. Subsequently, the specimens were pre-dried, dried and baked in accordance with NBR 7170 and NBR 8041. Under external quality control (visual inspection), the samples showed good porosity, homogeneity and conformation and were submitted to to density and compressive strength tests. The results obtained allow us to conclude that the addition of recycled paper pulp and crushed aluminized packaging (in a micro-mill), in small and certain proportions, to the clay does not damage the mechanical strength of ceramic bodies,
