AbstractGlass fiber reinforced cement pastes were prepared using a cement based on a hydraulically active glass in the system CaO-SiO2-Al2O3. The properties of such composites were compared with those made with ordinary portland cement.In all the studied materials the MOR and WOF values declined with time, however for different reasons.

Telah dilakukan penelitian tentang pengaruh persentase serat pelepah pisang terhadap sifat fisik dan mekanik papan semen. Persentase serat yang digunakan adalah 0%, 0,2%, 0,4%, 0,6% dan 0,8%. Penambahan serat pelepah pisang dan foam agent dapat membuat papan semen menjadi lebih ringan dibandingkan dengan papan Glass-Fiber Reinforced Cement (GRC) yang komersial. Hasil pengujian menunjukkan nilai densitas berbanding terbalik dengan porositas dimana nilai minimum densitas yaitu 1,27 g/cm3 terdapat pada serat 0,8%. Nilai porositas tertinggi terdapat pada persentase 0,8% yaitu 33,93%. Kuat tekan maksimum yaitu 82,76 kg/cm2 terdapat pada persentase serat 0,4% dan telah memenuhi SNI 03-3449-2002, sedangkan untuk nilai kuat lentur maksimum yaitu 77,40 kg/cm2 terdapat pada komposisi serat 0,6%. Hasil pengujian menyatakan papan semen serat pelepah pisang - foam agent telah memenuhi SNI 03-3449-2002 dengan nilai densitas <1,90 g/cm3.Kata kunci: papan semen, densitas, porositas, kuat tekan, kuat lentur, serat pelepah pisang.

Usage of Natural Fiber Composites (NFC) is increased rapidly due to the bio degradability nature of the fibers. These natural fibers are mixed with synthetic fibers to obtain better mechanical properties. In this study, pine apple and glass fiber reinforced epoxy composites are developed and their mechanical properties were evaluated. Composites were prepared by varying the fibers content and by using hand layup process with glass moulds of size 160 x 160 x 3 mm3 . The obtained laminates were sliced as per the ASTM criterion to test the properties. Higher glass fiber content in the composite specimen obtained higher mechanical properties. The composites can be utilized for the purpose of manufacturing components like doors panels, desks, roof tops etc.
