The test results appear in the concrete tensile strength values are obtained mixing coconut fiber at 1200 kg/m3 and the ratio of 600 kg/m have the same tensile strength values are obtained at the ksc in the concrete but the 1.64 omit coconut fiber.
Test results appear The tensile strength of concrete mixed with coconut fiber ratio of 1,200 kg / m3 and 600 kg / m has a tensile strength equal to 1.64 ksc. But that does not put coconut fibers in concrete.
The test results showed that The tensile strength of concrete mixed with coconut fiber ratio, and 1 200 kg / m3 600 kg / m the tensile strength only at the 1.64 KSC.? But in the concrete without the coir fiber
