Abstract
ABSTRAK Paving block merupakan produk bahan bangunan dari semen yang digunakan sebagai salah satu alternatif penutup atau pengerasan tanah. Salah satu bahan yang dapat digunakan untuk campuran paving block beton adalah dengan memanfaatkan sisa pembakaran batu bara yaitu fly ash. Dengan kandungan silika yang cukup tinggi ini memungkinkan abu batubara memenuhi kriteria sebagai bahan yang memiliki sifat semen/pozzolan sehingga dapat digunakan untuk mengurangi jumlah semen sebagai material penyusun beton contohnya dalam industri pembuatan paving block. Metode pembuatan paving block beton dilakukan secara mekanis menggunakan alat mesin (press) dan manual. Penelitian ini juga dilakukan untuk mengetahui komposisi semen dan tekanaan press yang optimal dalam pembuatan paving block beton sehingga mendapatkan mutu paving block beton yang lebih baik. Hasil penelitian menunjukan bahwa Kuat tekan optimal paving block beton manual (PBB manual) didapat pada paving block beton manual (PBB manual) batu pecah 30% dengan kadar fly ash 25% yaitu 27,76 MPa (mutu B). Sedangkan Kuat tekan optimal paving block beton press (PBB press) didapat pada paving block beton press (PBB press) batu pecah 30% dengan kadar fly ash 35% yaitu 27,58 MPa (mutu B) sedangkan Pada perhitungan penyerapan air dapat disimpulkan bahwa terjadi peningkatan penyerapan air terhadap paving block beton. Hal ini mungkin dikarenakan paving block beton dengan penambahan batu pecah 1mm–2mm membuat paving block mempunyai rongga-rongga kecil didalamnya. Kata Kunci: Paving Block, Fly Ash, Kuat Tekan , Penyerapan Air ABSTRACT Paving block is a product of building materials from cement which is used as an alternative to cover or to harden the soil. One of the materials that can be used to mix concrete paving blocks is to use the remaining coal combustion, namely fly ash. With this high silica content, it allows coal ash to meet the criteria as a material that has the properties of cement / pozzolan so that it can be used to reduce the amount of cement as a concrete building material for example in the paving block manufacturing industry. The method of concrete paving blocks making is conducted mechanically using a machine (press) and manually. This research was also conducted to determine the composition of cement and press pressure which are optimal in making concrete paving blocks so as to obtain better quality concrete block paving. The research results showed that the optimal compressive strength of manual concrete paving blocks (PBB manual) was obtained on manual concrete paving blocks (PBB manual) 30% split stone with 25% fly ash content which was 27.76 MPa (quality B). Meanwhile the optimal compressive strength of press concrete paving blocks (PBB press) was obtained on press concrete paving blocks (PBB press) 30% split stones with 35% fly ash content which was 27.58 MPa (quality B) while in the calculation of water absorption can be concluded that there is an increase in water absorption against concrete paving blocks. This might be due to concrete paving blocks with the addition of 1mm-2mm split stones making the paving blocks have small cavities inside. Keywords: Paving Block, Fly Ash, Compressive Strength, Water Absorption
