摘要：

The compatibility of oil-palm-trunk fibers and cement was investigated. Cold-water and hydrothermal carbonization treatments were applied on the fibers, and then the hydration temperature was measured to observe the compatibility. Calcium chloride (CaCl2), as an accelerator, was added at 1.5, 3.0, 4.5 and 6.0% of cement weight. The results showed that cold-water treatment and hydrothermal carbonization of the fibers reduced the hemicelluloses and ash content, thereby increasing the compatibility. Fourier transform infra-red analysis showed that functional groups of untreated and treated fibers were almost identical, indicating that the addition of treated fibers did not interfere the hardening process of cement. The treatment of fibers resulted in reduced thermal stability of the cement-fibers mixture, and the addition of CaCl2 decreased the hydration temperature of the mixtures, indicating that the chemical accelerated the hardening of the cement-fibers mixture. The addition of 1.5% CaCl2 to the cement mixture with treated fibers was adequate to obtain a low inhibitory index. Field emission scanning electron microscopy showed that higher formation of calcium silicate hydrate and calcium carbonate was observed in the treated fibers compared to the untreated fibers. The board modulus of elasticity increased by 215% and 281% after the fibers underwent with cold-water treatment and hydrothermal carbonization, respectively.
