Abstract

Berbagai percobaan dan penelitian dalam mencari bahan alternatif pembuatan paving telah dilakukan. Teknologi bahan dan teknik pelaksanaan yang diperoleh dari hasil penelitian dan percobaan tersebut dimaksudkan untuk menjawab tuntutan memperoleh komposisi atau bahan paving yang efektif dan efisien yang juga dapat mengurangi limbah industri. Penggunaan paving block sangatlah mendukung go green yang telah dikumandangkan secara nasional/internasional, karena daya serap air melalui pemasangan paving block dapat menjaga keseimbangan air tanah. Untuk memenuhi kualitas paving block maka perlu dilakukan percobaan dan penelitian dalam pembuatan paving block. Penelitian ini bertujuan untuk mengetahui komposisi paving block geopolimer dan pengaruh semen geopolimer terhadap paving block menggunakan variasi molaritas menggunakan metode kering. Berdasarkan penelitian Aaron Darius Vaz paving geopolimer mendapatkan kuat tekan yang cukup tinggi yang mencapai 69 Mpa dengan variasi molaritas 8-12 molar menggunakan fly ash tipe f dengan metode basah. Penelitian ini dilakukan dengan metode eksperimen dan material dalam penelitian ini terdiri dari kerikil, pasir, air, fly ash, NaOH, dan Na2Sio3. Perbandingan komposisi yang digunakan yaitu bahan pengikat : bahan pengisi sebesar 65% : 35% dan 70% : 30%, fly ash : alkali aktivator 70% : 30% NaOH : Na2Sio3 sebesar 1 : 2,5 dengan variasi 10 dan 12 molar dengan curing udara. Pengujian ini menggunakan mesin cetak paving Multi Block SB-305 dan jenis pengujian yang dilakukan pada penelitian ini yaitu uji kuat tekan, uji aus, dan uji penyerapan air. Berdasarkan hasil analisis yang telah dilakukan didapatkan kuat tekan pada umur 28 hari masing-masing sebesar 38 Mpa untuk PG 1-1, 30 Mpa untuk PG 2-1, 54 Mpa untuk PG 1-2, dan 40 Mpa untuk PG 2-2, Sehingga dapat diklasifikasikan memenuhi syarat sebagai paving block tipe B. Kuat tekan maksimum diperoleh pada variasi perbandingan bahan pengisi : bahan pengikat 65% : 35% dengan konsentrasi NaOH 12 Molar dan dapat diklasifikasikan memenuhi syarat mutu A menurut SNI 03-0691-1996. Hasil pengujian aus pada umur 28 hari dapat disimpulkan bahwa ketahanan aus rata-rata memenuhi klasifikasi tipe A menurut SNI 03-0691-1996. Hasil pengujian penyerapan air dapat disimpulkan bahwa rata-rata penyerapan air memenuhi klasifikasi paving block tipe B menurut SNI 03-0691- 1996.

Various experiments and studies in the search for alternative materials for paving making have been carried out. The material technology and implementation techniques obtained from the results of research and experiments are intended to answer the demands of obtaining effective and efficient compositions or paving materials that can also reduce industri waste. The use of paving blocks is very supportive of going green which has been proclaimed nationally / internationally, because water absorption through the installation of paving blocks can maintain groundwater balance. To meet the quality of paving blocks, it is necessary to conduct experiments and research in making paving blocks. This study aims to determine the composition of geopolymer paving blocks and the influence of geopolymer cement on paving blocks using molarity variations using the dry method. Based on the research of Aaron Darius Vaz paving geopolymers get a fairly high compressive strength that reaches 69 Mpa with a molarity variation of 8-12 molars using f- type fly ash with the wet method. This research was conducted by experimental methods and the material in this study consisted of gravel, sand, water, fly ash, NaOH, and Na2Sio3. The comparison of the composition used is binding materials: fillers by 65% : 35% and 70% : 30%, fly ash : alkaline activator 70% : 30% NaOH : Na2Sio3 by 1 : 2.5 with variations of 10 and 12 molars with air curing. This test uses a Multi Block SB-305 paving printing machine and j enis tests carried out in this study, namely compressive strength tests, wear tests, and water absorption tests. Based on the results of the analysis that has been carried out, the compressive strength at the age of 28 days is 38 Mpa for PG 1-1, 30 Mpa for PG 2-1, 54 Mpa for PG 1-2, and 40 Mpa for PG 2-2, respectively, so that it can be classified as qualified as paving block type B. Maximum compressive strength is obtained at the variation in the ratio of filler materials: binder 65%: 35% with a NaOH concentration of 12 Molars and can be classified as meeting the A quality requirement according to SNI 03-0691-1996. The results of wear testing at the age of 28 days can be concluded that the average wear resistance meets the type A classification according to SNI 03-0691-1996. The results of the water absorption test can be concluded that the average water absorption meets the classification of paving block type B according to SNI 03-0691-1996.
