O res?duo do processo de recauchutagem do pneu ? de dif?cil degrada??o e sua deposi??o em aterros sanit?rios ? invi?vel, al?m de propiciar ? procria??o de insetos nocivos a sa?de humana. Este trabalho tem como objetivo demonstrar a viabilidade de um comp?sito cer?mico contendo fibra de pneu na fabrica??o de blocos para pavimenta??o. Ser?o abordados os processos de fabrica??o e montagem dos blocos produzidos e as v?rias formula??es estudadas com diferentes propor??es entre os elementos constituintes: brita, areia, cimento, e fibra de pneu. Foram determinadas as propriedades mec?nicas das diferentes formula??es. Concluiu-se que a adi??o da fibra de borracha fragilizou o concreto o que p?de ser verificado na an?lise microestrutural obtida atrav?s do MEV, que revelou a presen?a de poros e a baixa ader?ncia entre a fibra e a matriz (fibra de pneu/pasta de cimento). O comp?sito com fibra de pneu mais vi?vel, BCPB1(1/2), pode ser utilizado em locais de solicita??es leves como pra?as, cal?adas, ciclo vias entre outros como tamb?m na fabrica??o de meio fio e sarjetas, por apresentar resist?ncia mec?nica ? compress?o em torno de 20 MPa. / This work aims to demonstrate the feasibility of a ceramic composite containing fiber in the rubber manufacturing interlocking blocks. Gravel, sand, cement, rubber and fiber: the processes of manufacture and assembly of blocks produced and the various formulations studied with different proportions between the constituent elements were addressed. Mechanical properties were determined for the different formulations, compressive strength, diametral compressive strength, water absorption and apparent density, obeying the rules related to each property. It was concluded that the addition of rubber fiber gave the concrete studied resistance lower than conventional concrete which can be verified on the microstructural analysis obtained by SEM, which revealed the presence of pores and the low adhesion between the fiber and the matrix compression (tire fiber / cement paste). The composite of more viable tire BCPB1 (1/2) fiber can be used in places requests as light squares, pavements, roads and other cycle as well as in the manufacture of the curb and gutter, by having compressive strength in about 20 MPa
