Tensile Strength of Coconut Fiber Waste as an Organic Fiber on Concrete

Jeffrey Andre Delarue


Coconut fiber waste as waste material from processed fiber making from coco fiber is generally just thrown away and burned. This waste still has fiber properties in size 5 - 7 cm in diameter ranging from 0.2 to 0.7 mm. This study aims to treat waste so as to obtain fiber that can be utilized as organic fiber in fiber concrete. The fiber diameter used in the study was 0.32 mm, 0.35 mm, 0.37 mm, 0.49 mm and 0.65 mm. Further examined the chemical content and tested tensile strength. The results showed that the chemical content of the fiber, namely hemicellulose 7.46%, cellulose 42.90% and lignin 41.28%. The tensile test result gives an average tensile strength value of 18.2 N with an average tensile stress of 117.46 MPa with a standard deviation of 25.04
