Analisis Kuat Tekan Pada Paving Block Akibat Variasi Komposisi Fly Ash Dan Serat Pelepah Kelapa Sawit

Abstract

Tujuan dari penelitian ini adalah (1) membuat spesimen uji tekan sesuai standar material paving block dengan variasi komposisi Fly ash dan serat pelepah kelapa sawit, (2) menguji spesimen uji tekan sesuai standar material paving block dengan variasi komposisi Fly ash dan serat pelepah kelapa sawit, (3) menganalisis dan mengevaluasi nilai kuat tekan pada material paving block dengan penambahan variasi komposisi Fly ash dan serat pelepah kelapa sawit. Metode yang digunakan adalah pembuatan bahan dan uji tekan. Alat uji yang digunakan dalam penelitian ini yaitu mesin uji kuat tekan, timbangan digital, cetakan spesimen benda uji. Bahan yang digunakan dalam penelitian ini yaitu semen portland, pasir sungai berkualitas tinggi, air, fly ash, serat pelepah kelapa sawit. Hasil dari penelitian ini ialah pengujian spesimen uji tekan pada material paving block dengan variasi komposisi Fly ash dan serat pelepah kelapa sawit dilakukan menggunakan 4 Variasi Spesimen Mortal 1:1 1%, 1:2 1%, 1:1 2%, 1:2 2%. dan hasil analisis penelitian memberikan rekomendasi untuk pengunaan spesimen material paving block variasi komposisi Fly ash dan serat pelepah kelapa sawit yaitu spesimen 1M2SNFA komposisi Fly ash 13% dan serat pelepah kelapa sawit 2% kuat tekan rata-rata 22,94 Pa didapatkan nilai kuat tertinggi tertinggi. The objectives of this study are (1) to make pressure test specimens according to paving block material standards with variations in the composition of Fly ash and palm frond fiber, (2) to test pressure test specimens according to paving block material standards with variations in the composition of Fly ash and palm frond fiber, (3) to analyze and evaluate the compressive strength value of paving block material with the addition of variations in the composition of Fly ash and palm frond fiber. The methods used are material manufacturing and compressive testing. The test equipment used in this study is a compressive strength testing machine, digital balances, specimen prints of test specimens. The materials used in this study were portland cement, high-quality river sand, water, fly ash, palm frond fiber. The result of this study was the testing of compressive test specimens on paving block material with variations in the composition of Fly ash and palm frond fiber carried out using 4 variations of Mortal Specimens 1: 1, 1: 2 1%, 1: 1 2%, 1: 2 2%. and the results of the research analysis provide recommendations for the use of paving block material specimens, variations in the composition of Fly ash and oil palm frond fiber, namely specimens 1M2SNFA composition of 13% Fly ash and 2% oil palm frond fiber, average compressive strength of 22.94 Pa, obtained the highest highest strong value.
