Civil construction is an important sector in the analysis of the economic and social development
of Brazil and at the same time is seen as a problem sector in relation to its various faces,
 thus demonstrating concern about the negative environmental impact caused in its several areas,
consumption of natural resources or the generation of large volumes of waste. The present work has
the objective of verifying the technical viability of the incorporation of kraft paper fibers obtained
by the recycling of cement bag packages in formulations of structural ceramic blocks. Initially, the raw
m'aterials used for the production of blocks were characterized by chemical, mineralogical and thermal
analysis techniques. The specimens were extruded and burned at a temperature of 950 °C with
 the contents of 0%, 3%, 6%, 10% and 15% of cellulose fiber by weight. Technological trials of water absorption,
apparent porosity and bending rupture stress were carried out. The microstructure of the ceramics
was observed by scanning electron microscopy. The results showed beneficial alteration of the physical
and mechanical properties of the ceramic composite, making the incorporation of the fiber in the production
 of ceramic composites technically feasible.
