Siregar, Julius (2021) PENGARUH PENGGUNAAN SBR LATEX TERHADAP KUAT TEKAN DAN MODULUS ELASTISITAS BETON POROUS DENGAN MENGGUNAKAN RCA (RECYCLED COARSE AGGREGATE). Sarjana thesis, Universitas Brawijaya.
Abstract
Penggunaan beton konvesional yang terus meningkat seiring pembangunan infrastruktur yang pesat di Indonesia mengakibatkan lapisan kedap air semakin luas. Salah satu solusi yang dapat mengatasi permasalahan tersebut adalah beton porous dengan menggunakan agregat kasar daur ulang atau RCA (Recycled Coarse Aggregate). Namun, beton porous memiliki kekurangan yaitu ikatan antar agregat yang lemah. Bahan tambah atau admixture adalah material tambahan pengadukan beton yang telah diolah sebelum atau selama proses mixing berjalan. Pada penelitian ini, bahan tambah yang digunakan adalah SBR. Penggunaan SBR Latex pada campuran beton berongga dapat meningkatkan daya lekat agregat pada campuran beton porous. Pada penelitian ini dilakukan pengujian kuat tekan beton terhadap beton porous dengan variasi SBR Latex sebesar 5% dan 10% terhadap berat semen serta variasi penggunaan agregat kasar daur ulang sebesar 0% dan 100%. Pengujian kuat tekan beton sesuai dengan SNI 03-1974-1990. Selain itu, pengujian berat isi, berat jenis, penyerapan, dan void ratio berdasarkan SNI 1969:2008, ASTM C29, dan ASTM C1688. Pembuatan sampel beton menggunakan perbandingan campran semen dengan agregat sebesar 1:4 dan nilai faktor air semen (FAS) sebesar 0,27. Penggunaan RCA pada pembuatan beton porous mengakibatkan penurunan kuat tekan beton berpori dibandingkan penggunaan NCA dan nilai modulus elastisitas RCA lebih rendah dibandingkan NCA. Hal ini disebabkan oleh mutu RCA yang lebih rendah dari pada NCA. Penggunaan SBR Latex pada pembuatan beton porous dapat meningkatkan kuat tekan beton. Pada pengujian beton porous dengan 5% SBR latex terjadi peningkatan kuat tekan beton sebesar 15,21% pada penggunaan NCA dan 22,3% pada penggunaan RCA. Beton porous dengan penambahan 10% SBR latex terjadi peningkatan sebesar 47,5% pada penggunaan NCA dan 65,87% pada penggunaan RCA.
English Abstract
The use of conventional concrete, which continues to increase along with the rapid development of infrastructure in Indonesia, has resulted in a more extensive waterproof layer. One solution that can overcome this problem is porous concrete using recycled coarse aggregate or RCA (Recycled Coarse Aggregate). However, porous concrete has a disadvantage, there is a weak bond between aggregates. Added material or admixture is additional material for mixing the concrete that has been processed before or during the mixing process. In this research, the admixture is SBR Latex. SBR Latex can increase the adhesion of aggregates in porous concrete mixtures. In this research, the compressive strength of concrete tested with SBR Latex variations of 5% and 10% of cement weight and variations of recycled coarse aggregate 0% and 100%. Concrete compressive strength testing is in accordance with SNI 03-1974-1990. Apart from that, test of content weight, specific gravity, absorption, and void ratio is based on SNI 1969: 2008, ASTM C29, and ASTM C1688. Making concrete samples using a cement mix ratio with aggregate of 1: 4 and a cement water factor (FAS) value of 0.27. The use of RCA in porous concrete resulted in a decrease in the compressive strength of porous concrete compared to NCA and the modulus of elasticity of RCA was lower than NCA. This is due to the lower quality of RCA than NCA. The use of SBR Latex can increase the compressive strength of concrete. In tested porous concrete with 5% SBR latex, there was an increase in the compressive strength of the concrete by 15.21% with NCA and 22.3% with RCA. Porous concrete with the addition of 10% SBR latex, there was an increase of 47.5% in with NCA and 65.87% with of RCA.
