Previous issue date: 2011-07-29 / To take care of to the demand of the new constructions in the low income communities
and to develop the production of a strengthened alternative brick with staple fibers of
coconut, capable to contribute mainly with the recycling of the green and mature coconut
in the urban and agricultural lexes, this research was developed, to confection bricks of
soil-cement with coconut fiber. Ecologically correct material and of low cost, since the
greenhouse use of or oven for burning will be manufactured without. The study it
presents a set of tables and graphs that prove good indices found in the values of the
density, water absorption, axial compressive strength and isolation term acoustics, with
evidential results that make possible the production in industrial character with press
mechanics or the place of the workmanship with manual form. The preparation of
coconut staple fibers was made of natural form without use of chemical products not to
deprive of characteristics the properties mechanical physicist-chemistries and of the same
ones. The sixty bricks produced in simple and manual press had been carried through in
four lots of fifteen units. The mixture of aggregates was made in four different traces
composites for: ground erinaceous, cement, fiber of dry coconut and water; the bricks had
been compact in the press and cured in natural way under an area covered during the
minimum time of seven days / Para atender a demanda das novas constru??es nas comunidades de baixa renda e
incrementar a produ??o de um tijolo alternativo refor?ado com fibras de coco, capaz de
contribuir principalmente com a reciclagem do coco verde e maduro nos lix?es urbanos e
rurais, foi desenvolvida essa pesquisa, para confeccionar tijolos de solocimento com fibra
de coco. Material ecologicamente correto e de baixo custo, j? que ser? fabricado sem o
uso de estufa ou forno para queima. O estudo apresenta um conjunto de tabelas e gr?ficos
que comprovam bons ?ndices encontrados nos valores da densidade, absor??o de ?gua,
resist?ncia ? compress?o axial e isolamento termo ac?stica, com resultados
comprobat?rios que possibilitam a produ??o em car?ter industrial com prensa mec?nica
ou no local da obra com f?rma manual. A prepara??o das fibras de coco foi feita de forma
natural sem uso de produtos qu?micos para n?o descaracterizar as propriedades f?sicoqu?micas
e mec?nicas das mesmas. Os sessenta tijolos produzidos em prensa simples e
manual foram realizados em quatro lotes de quinze unidades. A mistura dos agregados foi
feita em quatro tra?os diferentes compostos por: solo arenoso, cimento, fibra de coco seco
e ?gua; os tijolos foram compactados na prensa e curados em meio natural sob uma ?rea
coberta durante o tempo m?nimo de sete dias
