Pemanfaatan Serat Ijuk Pendek dalam Pembuatan Beton Ringan terhadap Sifat Mekaniknya

Abstract

Concrete with a mixture of short palmyra fiber was made by submersion time 28 days. Mechanical and physical propertiesof the samples: compressive strength, density, and water absorbtion has been determined by ASTM and SNI standard. The fibre composition varies for 0%, 2,5%, 5%, 7,5%, and 10%.The result showed that the best composition is 2,5% of short palmyra fiber. The value of Compressive Strength is between 7,02 MPa – 25,61 MPa, Density: 2,10 gr/cm2- 2,32 gr/cm2, and Water Absobtion: 1,5%-3,5%.
