Mechanical Properties of Bamboo as Green Materials to Reduce the Global Warming Effect
Keywords:deforestation, global warming, bamboo, mechanical properties
Global warming causes an increase in average temperatures on Earth. Over the past decade there has been 13 million ha / year deforestation. South America and Africa experienced the highest deforestation rates (> 3.4 million ha / year) and Asia also experienced forest loss in many places. To restore the preservation of the forest is needed plants that grow fast and able to absorb more carbon than crops. Bamboo is known as one of the fastest growing plants in the world, with growth rates ranging from 30 to 100 mm per day in its infancy. Due to the rapid accumulation of biomass and the effective fixation of solar and carbon dioxide energy, the carbon sequestration ability of bamboo tends to be second to none compared to other plants. According to estimates, a quarter of the biomass in the tropics and a fifth in the subtropical region comes from bamboo. For the construction materials the effect of bamboo treatment on bamboo mechanical properties requires further assessment. Testing mechanical properties is done after the specimen on the dry conditions of the furnace. Water content of specimens in the range of 12 - 13% in accordance with ISO 3129-1975 standards. Analysis of Variance (Anova) bamboo treatment with lateral stress as a construction material has an effect on bamboo mechanical properties. In strong bending, tensile strength and bamboo shear strength with lateral stress up to 2.5 MPa have no significant effect on bamboo properties. While on Eastic Modulus of Elasticity and bamboo compressive strength with lateral stress up to 2.5 MPa have significant effect on bamboo properties.
