Abstract

Abstrak Limbah kaca menyebabkan masalah lingkungan yang kronis karena sangat sulit terurai di dalam tanah. Kaca banyak digunakan dalam kehidupan sehari-hari melalui produk manufaktur seperti kaca lembaran, botol, dan barang pecah belah. Kaca adalah bahan yang berpotensi besar untuk didaur ulang. Penggunaan kaca daur ulang membantu dalam penghematan energi dan perbaikan lingkungan. Meningkatnya kesadaran akan daur ulang kaca mempercepat perubahan penggunaan limbah kaca dengan bentuk berbeda di berbagai bidang. Salah satu kontribusinya yang signifikan adalah pada bidang konstruksi dimana limbah kaca digunakan kembali untuk produksi beton. Sifat-sifat beton yang mengandung limbah kaca sebagai agregat halus diteliti dalam penelitian ini. Limbah kaca digunakan sebagai pengganti sebagian agregat halus pada campuran beton 20%, 40%, 60%, 80% dan 100%. Kuat tekan beton umur 3, 7, 14, 21 dan 28 hari dibandingkan dengan beton yang dibuat dengan agregat halus alami (beton normal). Hasil tersebut membuktikan bahwa kekuatan tertinggi diberikan oleh limbah debu kaca setelah 28 hari. Kuat tekan benda uji dengan variasi limbah kaca 20% dan 40% memiliki kuat tekan melebihi dari kuat tekan rencana (24,95Mpa), masing-masing 26,290Mpa dan 25,602 Mpa atau melebihi 5,4% dan 2,6%. Jika dibandingkan dengan kuat tekan rata-rata beton dan beton karakteristik beton normal, semua variasi limbah kaca mengalami penurunan. Di masa depan, penggunaan limbah kaca dalam beton ramah lingkungan akan memberikan dampak yang baik untuk konservasi sumber daya alam. Kata kunci: Kaca, beton, kuat tekan, ramah lingkungan.  AbstractGlass waste causes chronic environmental problems because it is very difficult to decompose in the soil. Glass is widely used in everyday life through manufactured products such as flat glass, bottles and glassware. Glass is a material with great potential for recycling. The use of recycled glass helps in saving energy and improving the environment. Increasing awareness of glass recycling is accelerating the change in the use of different forms of glass waste in various fields. One of its significant contributions is in the construction sector where glass waste is reused for concrete production. The properties of concrete containing glass waste as fine aggregate were investigated in this study. Glass waste is used as a partial replacement for fine aggregate in 20%, 40%, 60%, 80% and 100% concrete mixtures. The compressive strength of concrete aged 3, 7, 14, 21 and 28 days was compared with concrete made with natural fine aggregate (normal concrete). These results prove that the highest strength is given by the waste glass dust after 28 days. The compressive strength of the test specimens with variations of glass waste of 20% and 40% had compressive strength exceeding the design compressive strength (24.95MPa), respectively 26.290MPa and 25.602MPa or exceeding 5.4% and 2.6%. When compared with the average compressive strength of normal concrete and compressive strength of normal concrete characteristics, all variations of glass waste have decreased. In the future, the use of glass waste in environmentally friendly concrete will have a good impact on the conservation of natural resources. Keywords: Glass, concrete, compressive strength, environmentally friendly.
