Abstract

Need for the use of reinforced concrete in housing construction will increase along with the rapid population growth. This increases the need for steel reinforcement as a major component. The increase in need for steel reinforcement will trigger a price increase so that it becomes expensive and scarce. Iron ore as a raw material for making steel reinforcement is a mineral that can not be renewed. Therefore, efforts to use alternatives to steel reinforcement in concrete. Bamboo has good mechanical properties and a high ratio between strength and weight. Bamboo has a tensile strength is high, between 100-400 MPa, nearly matching the tensile strength equivalent to steel reinforcement ½ to ¼ of iron ultimate voltage (Widjaja, 2001) and (Surjokusumo and Nugroho, 1993) showed similar results and by the Moriscos, 1996 that the tensile strength of bamboo can reach 1280 kg / cm2. Bamboo can be used as the material of reinforced concrete. This study aims to determine the capacity of the bending beam with reinforcement of bamboo, bamboo reinforced beam deflection capacity. This experiment is a concrete beam bending test. The results showed that bamboo reinforced concrete beam has a maximum capacity reached 56.61% of the maximum capacity of steel reinforced concrete.

Abstract

This study is a follow-utilization of water hyacinth as a building material wall panel (Emen wall). From previous studies, physical properties, mechanical, acoustic and endurance burn this material meets the standards of building materials PUBI 1982 and ISO and ASTM C423-90a 03-6861.1-2002. In this study, the variable still is a variation of the test specimen without reinforcement with reinforcement of bamboo and bamboo in the form of a model variation of the beam section size (15x20cm) and sectional plates (5x15cm). While the independent variable is in the form of bending strength and deflection in the test specimen. The results showed the effect of bamboo reinforcement against bending strength cement panel hyacinth. On the test object model of the beam section with bamboo reinforcement ratio r = 0, r= 0.006 and r = 0.01 , powerful bending P = 24kg, P = 59kg and P = 72kg. To model the cross section of the plate with a bamboo reinforcement ratio r = 0, r = 0.017 and r = 0.025 , stronger bending is P = 3,33kg, P = 16,33kg  and P = 21,83kg.
