Studi Kuat Tekan dan Kuat Lentur Beton Normal dengan Bahan Tambah Serat Nylon

Abstract

Concrete is a mixture consisting of materials such as coarse aggregate, fine aggregate, cement and added water. Concrete has many advantages for building construction. Among other things, high compressive strength, easy to maintain, easy to form and arrange. Therefore with this research will create different variations of normal concrete using Nylon fiber. Where nylon fiber has elastic and tough properties so that it is expected to improve the compressive strength and normal bending of concrete. The purpose of this study was to determine the compressive and flexural strength of normal concrete with added nylon fiber. The results of this study obtained the compressive strength of normal concrete at an average age of 14 days, namely 6.30 MPa and 28 days of age, namely 4.60 MPa. While mixing 5% nylon at 14 days is 5.31 Mpa and 28 days is 5.01 Mpa. The flexural strength results of normal concrete aged 13 days are 2.18 MPa and those aged 28 days are 2.63 MPa. Meanwhile, with the addition of 5% nylon at the age of 14 days, it is 2.22 MPa and at the age of 28 days, it is 2.68 MPa. The results of this study are not in accordance with the 2010 Bina Marga Specifications.
