Marsoli, Ayuning Fitriani (2020) Pengaruh Penggunaan SBR Latex Terhadap Kuat Tekan dan Permeabilitas Beton Porous. Sarjana thesis, Universitas Brawijaya.
Abstract
Beton porous adalah beton berpori yang dapat digunakan untuk melapisi permukaan jalan dengan beban rendah sebagai pengalir air agar tidak menggenang di muka jalan dan selanjutnya diteruskan ke dalam tanah. Hal ini dapat menjadi solusi dari permasalahan genangan di beberapa daerah di Indonesia. Material yang digunakan pada penelitian ini adalah agregat kasar dengan ukuran 5 mm – 10 mm dan menggunakan campuran zat tambahan (additive) yaitu SBR Latex yang berfungsi untuk menambah kekuatan ikatan antara pasta dengan agregat maupun antar agregat. Dengan penambahan SBR Latex diharapkan dapat meningkatkan nilai kuat tekan serta dapat mengetahui pengaruh penambahannya terhadap permeabilitas beton porous. Penelitian ini dilaksanakan dengan menggunakan alat Compression Test Machine untuk pengujian kuat tekan, serta metode Falling Head untuk pengujian Permeabilitas. Benda uji beton porous menggunakan variasi campuran SBR Latex yaitu : 0%, 5%, dan 10%. Rasio volume semen terhadap agregat yang digunakan pada penelitian ini sebesar 1:3 dan 1:4. Serta menggunakan faktor air semen sebesar 0,25 dan 0,27. Hasil akhir penelitian didapatkan nilai kuat tekan tertinggi yaitu 12,4 MPa terdapat pada benda uji dengan komposisi SBR Latex 5%, rasio volume semen terhadap agregat 1:3, dan faktor air semen 0,25. Hasil kuat tekan beton semakin menurun seiring dengan penambahan kadar SBR Latex. Penggunaan kadar SBR Latex optimum dapat meningkatkan kuat tekan beton porous. Sedangkan hasil akhir penelitian untuk permeabilitas didapatkan nilai koefisien permeabilitas tertinggi yaitu 12,97 mm/dt pada sampel dengan kadar SBR Latex 0%, rasio volume semen terhadap agregat 1:4 dan faktor air semen 0,25. Hal ini selaras dengan fungsi SBR Latex sebagai pengikat dan zat tambahan.
English Abstract
Porous concrete is a porous concrete that can be used to cover the road surface with a low load as a water drain, so as not to puddle in the face of the road and then forwarded into the ground. This can be a solution to the problem of inundation in several regions in Indonesia. The material used in this study is coarse aggregate with a size of 5 mm - 10 mm and uses a mixture of additives, namely SBR Latex which serves to increase the bond strength between the paste with the aggregate or between aggregates. With the addition of SBR Latex, it is expected to increase the compressive strength value and to know the effect of the addition to the permeability of porous concrete. This research was conducted using the Compression Test Machine for compressive strength testing, as well as the Falling Head method for permeability testing. Porous concrete specimens using SBR Latex mixture variations namely: 0%, 5%, and 10%. The agregate-to-cement ratio used in this study is 1: 3 and 1: 4, and using the waterto-cement of 0,25 and 0,27. The final results of the study obtained the highest compressive strength value of 12,4 MPa found in the specimen with 5% SBR Latex composition, agregate-to-cement ratio of 1:3, and water-to-cement ratio 0,25. The compressive strength of porous concrete decreases along with the addition of SBR Latex. The use of SBR Latex increased compressive strength of porous concrete. While the final results of the study for permeability obtained the highest permeability coefficient value is 12,97 mm/sec with 0% of SBR Latex, agregate-to-cement ratio of 1: 4 and water-to-cement ratio of 0,25. This is in line with SBR Latex's function as a binder and additive.
