  • 11. Analysis and Result SUMMARY DENSITY OF BRICK FOR COMPRESSIVE STRENGTH NYLON FIBRE LATERITE BRICK (TESTED IN WET CONDITION) Based on the observation Table 1.1 and Figure 1.0, the higher the nylon fibre content is added to a mixture of laterite bricks will make decreases the density of laterite bricks. This is because the graph shown in Figure 1.0 declining from 2121.70 kg/m3 to 1920.08 kg/m3. The decrease of the density was due to the replacement of heavy constituent material in the bricks, which were cement and laterite soil by nylon fibre, which consequently reduced the weight and also the density of the brick. More nylon fibre, resulted in lower density of bricks.

SUMMARY DENSITY OF BRICK FOR COMPRESSIVESTRENGTH AND WATER ABSORPTION NYLON FIBRELATERITE BRICK (TESTED IN DRY CONDITION)Based on the observation Table 1.2 and Figure 1.1, the higher the nylonfibre content is added to a mixture of laterite bricks will makedecreases the density of laterite bricks. This is because the graphshown in Figure 1.1 declining from 2088.67 kg/m3 to 1867.00 kg/m3.

  • 16. Based on the observation Figure 1.2, both wet and dry bricks showsthat the higher the nylon fibre content is added to a mixture oflaterite bricks will make decreases the density of laterite bricks. Thebrick type sample B (1 % of nylon fiber) for dry bricks condition andsample B (1 % of nylon fibre) for wet bricks condition gave thehighest density among other type of bricks.Other than that, the decrease of the density was due to thereplacement of heavy constituent material in the bricks, which werecement and laterite soil by nylon fibre, which consequently reducedthe weight and also the density of the brick. More nylon fibreresulted in lower density of bricks.

SUMMARY OF COMPRESSIVE STRENGTH NYLONFIBRE LATERITE BRICK (TESTED IN WET CONDITION)Based on the observation Table 1.3 and Figure 1.3, the higher the nylonfibre content is added to a mixture of laterite bricks will makedecreases the strength of laterite bricks.

SUMMARY OF COMPRESSIVE STRENGTH NYLONFIBRE LATERITE BRICK (TESTED IN DRY CONDITION)Based on the observation Table 1.4 and Figure 1.4, the higher the nylonfibre content is added to a mixture of laterite bricks will makedecreases the strength of laterite bricks. This is because the graphshown in Figure 1.4 declining from 7.320 kN/m 2 to 5.786 kN/m 2.

  • 22. Based on the observation Figure 1.5, both compressive strengthtests shows that the higher the nylon fibre content is added to amixture of laterite bricks will make decreases the strength of lateritebricks. The brick type sample B (1 % of nylon fibre) for dry brickscondition and sample E (4 % of nylon fibre) for wet bricks conditiongave the highest compressive strength among other type of bricks.The boiling up of fibres was observed on the samples with high fibrecontents (2 – 5 %) which may contribute to the reduction of thecompressive strength. This may be due to discontinuity of the brickmaterial.

  • 24. SUMMARY OF WATER ABSORPTION LATERITE BRICKWITH FIBRE NYLONBased on Table 1.5, the average water absorption of laterite brickssample with nylon fibre content is 5.255 % while its standard deviationis 1.65 %. It was observed that laterite bricks control has the ability canabsorb water at a moderate rate amongst of laterite bricks with nylonfibre.Based on the observation Figure 1.6, water absorption test shows thatthe higher the nylon fibre content is added to a mixture of lateritebricks will make increases the water absorption of laterite bricks. Fromthe graph shown in Figure 1.6, water absorption for sample (B to F)rising from 3.491% to 8.239%.The water absorption increased with further additional of fibres, maybe due to the discontinuity of the brick material, which induced morewater to be absorbed. Other reason may be due to the boiling up ofthe fibre which also resulted in case discontinuity of the material,hence more water can be absorbed.

  • 27. Conclusion The major point of this research was to study the effect of addition of nylon fibres into the laterite bricks. The study focused on the physical and mechanical properties of laterite bricks with nylon fibre. The physical properties studied were dimensions, density, water absorption and the mechanical property was the compressive strength. The following findings have been established from the research; 1) The density of laterite bricks with nylon fiber decreased with the increased in fiber content added to the bricks where the value decreased from 2088.67 kg/m3 to 1867.00 kg/m3. 2) The an increased in nylon fibers content has resulted in the increase of compressive strength of laterite bricks with nylon fiber which the highest was 7.320 kN/m2 compared to 5.514 kN/m2 brick control. This might be due fibres had successfully reinforced other constituent material of laterite bricks with nylon therefore increase the compressive strength.
  • 28. 3) It was found that addition of fibre nylon did improve the compressivestrength which range from 7.320 kN/m2 to 5.711 kN/m2. The balling upof fibres was observed on the samples with high fibre contents (2% to5%) which may contribute to the reduction of the compressive strength.4) Water absorption of low fibre content laterite bricks with nylon (1%)was lower than the water absorption of control brick. It is believed thefibres had effectively reinforced other constituent material of lateritebricks with nylon thus minimize the porosity of the bricks and lower thewater absorption.5) The water absorption of bricks in laterite bricks with nylon fiberincreased with the increased in the addition of fiber contents.6) The water absorption increased with further addition of fibres (1% to5%), may be due to the discontinuity of the brick material which inducedmore water to be absorbed.
  • 29. 7) Overall, it can be concluded the addition of nylon fibre had improvedthe density and compressive strength of laterite brick, howevercontributed to high water absorption of the brick.
