    Abstract

    This paper investigated the mechanical properties of brick earth blocks filled by coconut fibres in order to enhance the blocks strength. The development of coconut fibres in brickearth blocks will provide a lot of benefits to local usage and industries as they offer a low cost product and are also environmentally friendly. In this framework, a series of blocks were fabricated using a soil and fibres, then compacted with a dynamic stress compaction. The blocks have been dried naturally for 7 days and 14 days respectively. The brickearth soil were tested and results analysis for identification of the characteristic of the soils have been present. Better result of the average compressive shear strength was observed by coconut fibre blocks with 2.0% of fibre in 14 days result. But for the remaining result, the addition of fibres under compaction pressure has an adverse effect on the properties of brickearth blocks. Impact of coconut fibres on the density of the blocks was unfavourable for 1.0% of fibre content due to the error in mixing the coconut fibres with the brickearth soil during the blocks production. It can be said by increasing the coconut fibre content in the soil blocks there is a general increase in average compressive shear strength. It was concluded from the results that the coconut fibre blocks can be used in housing construction particularly in walling.
