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, the moo fetched and flexibility of clay bricks are not related with tall natural and feasible values, particularly with regard to crude fabric sources and fabricating processes. Agricultural world is growing fast, with increased rural arrive development and land cultivation leading to massive development of the agro-based industry leading to expansive amount of agrarian squanders which are not recycled. Therefore, these wastes can be reused by reviving fibres obtained from disposed leaves and fruit bunches, which can be used in brick-making. This research investigated the mechanical properties of clay bricks built by including two naturally existing fibres to a clay-water blend, in heated and non-heated conditions. The fibre samples were sourced from pineapple leaves (PF), Coconut at the range of 0.5-1.5 % with length 5mm and 10mm. To that mixture, cement was mixed at 5 %, as it is a binder. It was observed that the two fibres had distinct after effects on the bricks produced and the presence of cement dominated the compressive strength. The non-baked bricks disintegrated when immersed in water and the baked ones exhibited cement-dependent qualities in water-absorption and density variations. Interestingly increase in fibre content did not cause significant density reduction in both the baked and non-baked bricks.
