Abstract:
The increasing of demand in paper usage among publication, education and private units causes in excessive paper waste. Even though there is campaign in using recycle papers, the waste papers
still increase. This research is to study the uses of office waste papers in combination with cement. In the study methodology, waste papers arc moisture with water for 7 days before put into cutting
machine to make paper fibers. The paper fibers then arc mixed with Portland cement type 1 with the mixture ratio ~f 1: 1.5, 1: 1.25, 1: 1, 1:0.75 and 1:0.50 in weight to produce the cubic specimens.
In preparing specimen, the pressure at 10 and 15 kg per sq cm are applied on the sample size 25x40x1O cm. The sample is then cut into 6 pieces with dimension 10x1Oxi0 cm for studying the
mechanical properties under force applied. The result indicates that the mixture ratio of cement 1 to paper fiber 1.25 with applied pressure 15 kg per sq cm has the most appropriate to be used for paper
fiber cement. The sample from such mixture has density at 796.33 kg per eu m, vertical compressive load resistance capacity at 27.44 kg per sq cm, and water absorption rate at 466 kg per cu m. The results also show that paper fiber mixing concrete has excellent properties in both density and water absorption. These properties pass the required specification of TIS 2505-2541 class 4. The compressive resistance, however, docs not satisfy the requirement of TIS. 2505-2541
