Experimental study on compressive strength of brick using natural fibres

Abstract

Despite the use of modern materials, clay bricks are reasonably preferable materials nowadays. However, themoofetchedandflexibilityof claybricks are not related with tall natural and feasible values, particularly withregardtocrude fabric sources andfabricatingprocesses. Agricultural world is growing fast, with increased rural arrive development and land cultivation leading to massive development of theagro-basedindustry leadingto expansive amount of agrarian squanders which are not recycled. Therefore, these wastes can be reusedby reviving fibres obtained from disposed leaves and fruit bunches, which can be used in brick-making. This research investigated the mechanical properties ofclay bricks built by includingtwo naturallyexisting fibres to a clay-water blend, in heated andnon-heatedconditions. The fibresamples were sourcedfrompineapple leaves (PF), Coconut at the range of 0.5-1.5% with length 5mmand10mm. To that mixture, cement was mixed at 5 %, as it is a binder. It was observedthat the two fibres had distinct after effects on the bricks produced and the presence of cement dominatedthe compressive strength. The non-baked bricks disintegrated when immersedin water andthe bakedones exhibitedcement-dependent qualities in water-absorption and density variations. Interestingly increasein fibre content didnot cause significant density reduction in both the baked and non-baked bricks.
