Abstract

Beton Self Compacting Concrete (SCC) merupakan inovasi material beton yang mampu mengalir dan memadat dengan sendirinya tanpa bantuan alat getar. Salah satu permasalahan yang dihadapi dalam pengembangan beton SCC adalah tingginya kebutuhan agregat halus (pasir), yang berdampak pada eksploitasi sumber daya alam. Penelitian ini bertujuan untuk menganalisis pengaruh substitusi limbah plastik ABS sebagai pengganti sebagian agregat halus terhadap karakteristik dan kuat tekan beton SCC sekaligus memberikan kontribusi positif terhadap lingkungan. Variasi substitusi yang digunakan yaitu 0%, 5%, 7,5%, 10%, 12,5%, dan 15% terhadap volume pasir. Pengujian dilakukan terhadap karakteristik beton segar sesuai pedoman EFNARC 2005, serta pengujian kuat tekan pada umur beton 7, 14, dan 28 hari mengacu pada metode SNI 1974:2011. Hasil penelitian menunjukkan bahwa penambahan limbah plastik ABS meningkatkan workability beton SCC seiring dengan kenaikan kadar substitusi disebabkan oleh permukaan limbah plastik ABS yang licin sehingga mengurangi gesekan antar campuran beton. Namun, kuat tekan mengalami penurunan disebabkan oleh adhesi pada beton berkurang karena ikatan antara pasta semen dengan plastik ABS lemah dikarenakan permukaannya yang licin, pada kuat tekan menunjukan beton SCC dengan Substitusi limbah plastik ABS pada agregat halus menurun terjadi pada kadar berturut- turut dari variasi dengan hasil kuat tekan maksimum pada umur 28 hari memiliki rata-rata kuat tekan berturut-turut dari variasi paling rendah adalah 29.64 MPa, 29.30 MPa, 28.46 Mpa, 27.01 Mpa dan 25.19 Mpa dibandingkan beton kontrol yaitu 30.16 MPa. Hal tersebut menunjukan persentase 5% limbah plastik ABS berpotensi sebagai alternatif yang ramah lingkungan pada substitusi parsial agregat halus dalam beton SCC dengan toleransi standar mutu beton struktural. Kata kunci: Beton Self Compacting Concrete (SCC), limbah plastik ABS, karakteristik, agregat halus, kuat tekan. Self-Compacting Concrete (SCC) is an innovative concrete material capable of flowing and compacting under its own weight without the need for vibration. One of the challenges in developing SCC is the high demand for fine aggregates (sand), leading to the exploitation of natural resources. This study aims to analyze the effect of substituting ABS plastic waste as a partial replacement for fine aggregates on the characteristics and compressive strength of SCC, while also contributing positively to the environment. The substitution variations used were 0%, 5%, 7.5%, 10%, 12.5%, and 15% of the sand volume. Tests were conducted on the fresh concrete characteristics following the EFNARC 2005 guidelines and compressive strength tests at 7, 14, and 28 days based on the SNI 1974:2011 method. The results showed that adding ABS plastic waste increased the workability of SCC as the substitution rate increased, due to the smooth surface of ABS plastic waste reducing friction among the concrete mix components. However, the compressive strength decreased because the adhesion in the concrete was reduced due to the weak bond between the cement paste and the ABS plastic, attributed to its smooth surface. The compressive strength results at 28 days showed that SCC with ABS plastic waste substitution in fine aggregates decreased progressively with higher substitution rates, with the average compressive strengths being 29.64 MPa, 29.30 MPa, 28.46 MPa, 27.01 MPa, and 25.19 MPa, compared to the control concrete at 30.16 MPa. This indicates that a 5% substitution of ABS plastic waste has the potential to serve as an environmentally friendly alternative for partial fine aggregate replacement in SCC, meeting the standard quality tolerance for structural concrete. Keywords : Self-Compacting Concrete (SCC), ABS plastic waste, characteristics, fine aggregate, compressive strength
