Abstract
Abstrak Serbuk kaca selain dijadikan sebagai bahan pengganti agregat halus juga dapat berfungsi sebagai pengganti semen karena memiliki potensi sebagai material pozzoland dengankandungan silica (SiO 2 ), Na 2 O dan CaO pada kaca cukup besar yaitu lebih dari 70%. Tujuan dari penilitian ini adalah untuk mengetahui pengaruh penambahan limbah kaca terhadap kuat tekan beton dan bagaimana tingkat kelecakan pada beton dengan campuran limbah kaca. Peneltiian ini menggikuti metode SNI 03-2834-2000, menggunakan beberapa presentase yaitu 0%, 12%, 15% dan 18%, dengan umur beton 28 hari. Dari masing-masing campuran beton tersebut dibuat tiga benda uji menggunakan silinder dengan diameter 15 cm dan tinggi 30 cm. Pengujian yang dilakukan pada beton tersebut adalah kuat tekan. Berdasarkan hasil penilitian dapat diperoleh nilai slump benda uji beton normal memiliki nilai rata-rata slump yang sesuai dengan mix design yaitu 10 cm. Untuk benda uji beton yang ditambah serbuk kaca mengalami penurunan dari beton normal. Beton campuran serbuk kaca dengan persentase 12% memiliki nilai slump yaitu 10,5 cm dan dan merupakan yang paling tertinggi dari beberapa presentase sedangkan nilai slump yang paling terkecil adalah pada presentase 18% nilai slump yaitu 10 cm. Pada pengujian kuat tekan didapatkan kuat tekan rata-rata beton normal 0% sebesar 22,25 Mpa, 12% sebesar 19,65 Mpa, 15% sebesar 19,69 Mpa, dan 18% sebesar 19,85 Mpa. Dari hasil kuat tekan yang didapat beton dengan campuran limbah kaca ini termasuk kategori beton mutu rendah, umumnya digunakan untuk struktur beton tanpa tulangan seperti beton siklop, trotoar, pasang batu kosong yang diisi adukan, dan pasangan batu. Kata kunci: beton, semen, serbuk kaca, kuat tekan Abstract Apart from being used as a substitute for fine aggregate, glass powder can also function as a substitute for cement because it has the potential as a pozzoland material with a large amount of silica (SiO 2), Na 2 O and CaO in glass, which is more than 70%. The purpose of this study was to determine the effect of adding glass waste on the compressive strength of concrete and the level of discomfort in concrete with a mixture of glass waste. This research followed the SNI 03-2834-2000 method, using several percentages, namely 0%, 12%, 15% and 18%, with a concrete age of 28 days. From each of these concrete mixtures, three specimens were made using a cylinder with a diameter of 15 cm and a height of 30 cm. The test carried out is on the concrete compressive strength. Based on the research results, it can be obtained that the slump value of normal concrete specimens had an average slump value in accordance with the mix design, which was 10 cm. For concrete specimens added with glass powder, it had decreased from normal concrete. Glass powder mixed concrete with a percentage of 12% had a slump value of 10.5 cm and was the highest of several percentages while the smallest slump value was at a percentage of 18%, the slump value is 10 cm. In the compressive strength test, the average compressive strength of normal concrete was 0% of 22.25 Mpa, 12% of 19.65 Mpa, 15% of 19.69 Mpa, and 18% of 19.85 Mpa. From the results of the compressive strength obtained by concrete with a mixture of glass waste, it was categorized as low quality concrete, generally used for unreinforced concrete structures such as cyclops, sidewalks, installing empty stones filled with mortar, and masonry. Key words: concrete, cement, glass powder, compressive strength
