Effect of Coconut Fiber Concrete on Tensile Strength of Concrete

Abstract

This research aims to determine the mechanical properties of the compound include coconut fiber mixed with concrete. It will provide concrete fasteners . The coconut fiber as a reinforcement . Toughness is being able to make more and more testing on the mechanical properties including compressive strength properties , that is, to find the most suitable concrete mix coconut fiber . What to wear , how much coconut fiber volume easily as possible. The first step of the method is tested . Properties of composite materials are mixed into the concrete. Using standard ASTM test the specific gravity of cement by the standard ASTM C 188-78, sand tested for specific gravity and absorption according to ASTM C128-88 test unit weight according to ASTM C29 and tested for standard size assorted ways . sieve according to ASTM C136-849, stone tested for specific gravity , absorption by ASTM C127-88, to test the unit weight of the rock standard ASTM C29 and tested for the corrosion with Los Angeles. Angelina , along with assorted sizes and testing methods of sieve standard ASTM C136-849. The second step is the values of the material properties of the test combinations. Calculate the weight by ACI fee dissolution at 8-10 cm. , And ultimate compressive strength at 240 ksc. The third step is to mix up the ingredients , including compounds such as concrete . Coconut fiber and fiber mesh Nemo 's number . Mixture at 600, 900 , 1200 grams , including 7 mix for the slump of the concrete as it was calculated or not. If you have concrete examples and jab into three layers , each 25 storey 63 samples , and then curing age of 3 , 7, and 28 days curing age specified then the very next determine the ultimate compressive strength . Test results show that The ultimate compressive strength of the concrete mix, coconut fiber, 600 g / m compression up to 524 ksc. , And concrete fiber mesh , there are no ads on 512 ksc. , But there are Agra 491 Concrete Mix Control . ksc. , which show that coconut fiber is the part that makes it more concrete compressive strength and can be used in real work. And can be used instead of synthetic fibers such as fine mesh has a number . But the amount specified in the input of the fiber in use.
