Abstract:
This research aims to develop the wafer paper fiber cement mixing for uses as the material replacement in interior wall. The used papers are soaked in water for 7 days, then changed to be
paper fiber. The paper fiber is mixed with concrete and prepared to be specimen 20x30x5 cm3 by pressing machine. The specimen is then cut into smaller pieces with dimension 5x5x5 cm3 for
studying the compressive load resistance. The specimen with size 20x30x1.5 cm3 is cut into IOx30x 1.5 cm3 sample for bending testing. The variables considered in this study are cement :
paper fiber mixture ratios which are 1: I , 1: 1.15 and 1:2. The compressive load test, the applied forces are 10, 17.5,25 and 50 ksc. For bending test, the mixing ratios are 1:1 and 1:1.5. The
pressure at 50 kg per sq cm is applied for sample molding. The types of paper for thin wafer are A4 paper, wall paper, 100 Ibs paper and aluminum foils. For thick wafer, the types of papers are beer
paper container, future-board, and wood plank. The results show that the sample with low mixing ratio of cement: paper fiber and with long curing has increasing in compressive resistance. The
mixing ratio of cement : paper fiber at 1: 1 yields the maximum compressive load resistance of 25 ksc at concrete age 28 days. For thin wafer type, 100 Ib papers has the most maximum load
resistance. For the thick wafer type, plank wood yields the most maximum compressive load resistance when the mixing ratio of cement: paper fiber is I: I. The conclusion is drawn that the
factors in quantity, type, and pressure used in building samples influences the compressive load and bending resistance of the wafer paper fiber cement mixing.
