Still today, in Brazil, the fibre cement to the base amianthus is the main fibrouscomposite to the base of main cement with wide production scale, despite verification ofits damages, as breathing diseases and cancer, caused by this fiber during the extractionprocess, production and installation. In the USA, European Union and Canada theproduction of materials to the base of amianthus are prohibited or they suffered seriousrestrictions. In Brazil, the federal government wile begin to extinguish the amianthusextraction in 2005 due to the problems used for amianthus writer allow, it is necessaryto get a new material with appropriate physical and mechanical properties, that is ecofriendlyand of appropriate cost.In this work the use of pulps bamboo cellulose s is analyzed, with two types oftreatment, which are pulps before the process of I refine and after this process, forreinforcement of main cimentícias, using the production process Hatschek in scalelaboratories. The pulps cellulose s was used in the percentages of 4, 6, 8, 10, 12, 14 and 16 per cent in relation to mass of the cement, being used the full head office as reference. Inaddition, it was substitution of the cement by a residue of the it manufactures of bricksin the proportion of 20, 30 and 40 per cent in relation to mass of the cement and two types ofequipment of different production. The aim of this work is to determine the idealpercentage of reinforcement for the two used types of pulps used, discussing thephysical properties, mechanics and microstructure of each one of these composites.
