| 520 | |a It is generally known that ordinary cement based composite have been occupied in industry because it is relatively low price and uncomplicated processing product. Even so, the concern is therefore lies in creation of environmental friendly with higher performance type cement based composite. The efforts currently is under way in producing lightweight cement composite with use of agriculture waste, coir fiber, and biopolymer, egg albumen in turn to reduce the use of Portland cement which at the same time provide composite with better properties. The effects of constituent compositions, rheological properties of albumen, curing process and fiber properties on the physical and mechanical properties of cement composite were studied. In this work, a promising cement based composites were fabricated via mixing, casting and curing process, an aqueous slurry containing cement powders with various amounts of egg albumen (55, 60, 65, 70 and 75 vol. %) were fabricated and been cured for 7, 14, 21 and 28 days. An optimum strength was obtained at samples incorporated with 65 vol. % of albumen and tested after 28 days of curing. Using the optimum ratio, it is necessary to investigate the effect of fiber content on the strength properties (flexural and compression) and physical characteristics (density, moisture content and water absorption) of coir fiber reinforced cement-albumen composite. Subsequently, composite samples were prepared by adding 1-11 % (by weight) of fiber to the slurry of egg albumen and cement, so that the ratio of albumen and fiber-cement was 65:35 (volume percent). The results indicate that the addition of fiber significantly improves the post-cracking flexural stress of composite. Optimum bending strength of 6.719 MPa was achieved at 5 wt. % fiber content after 35 days curing. An increase in fiber content results the decrease in density. These slightly increase the percentage of moisture content and water absorption. Owing to dissimilar in bonding strength, the fracture surfaces observed different hydration bond formed between fiber and matrix. These behavior correlates with the interfacial characteristics of fiber-matrix confirmed by SEM. Correspondingly, fiber length were varied to 2.5, 5, 10, 20 mm with fixed loading of 5 wt. %. The results showed that increasing in length-diameter ratio of fiber augment the flexural strength than short fiber. On the other hand, incorporation of long fiber into the cement results in low densities which slightly increase the water absorption and moisture content. For comparison, specimens of coir fiber reinforced water-cement composite with the same ratio and procedures was also prepared. Bending strength of ≈ 6.719 MPa was obtained for albumen-binder composite which is 65 % higher compared to water-cement composite. Basically, coir fiber reinforced cement-albumen composite specimens mark a significant innovation in which enhancement of the composite material in term of lightness (density) and strength. On the basis of the results, this is a good illustration of a holistic approach towards competent exploitation of natural resources, safe disposal of waste, and new making of high quality concrete. | ||
