Abstract

Beton ringan dihasilkan dengan cara pengurangan agregat kasar sehingga beton akan berpori atau berongga dan menghasilkan berat yang ringan. Untuk meningkatkan mutu beton tersebut maka ditambah material tambahan yaitu serat polypropylene (sejenis plastik mutu tinggi). Penelitian ini bertujuan untuk mengetahui pengaruh serat polypropylene sebagai material tambahan pada kuat tarik belah beton ringanserta mengetahui kadar persentase penambahan serat polypropylene paling optimum. Metodologi yang digunakan adalah eksperimen yang merupakan metode penelitian untuk mengetahui pengaruh tertentu. Penelitian ini menggunakan 3 variasi campuran dengan persentase 0.25%, 0.50%, 0.75% dengan jumlah benda uji 36 buah dan umur penggujian dimulai dari 7 hari, 14 hari serta 28 hari. Dari hasil pengujian uji kuat tarik belah didapat hasil pengujian umur 28 hari beton normal sebesar 1.38 MPa pada penambahan serat dengan variasi 0.25%, 0.50% serta 0.75% sebesar 1.54 MPa, 1.49 MPa dan 1.43 MPa. Didapat nilai optimum pada persentase 0.25% sebesar 1.54 MPa
