Abstract

Semen digunakan sebagai bahan utama komponen pengikat agregat pada beton. Penambangan batu kapur yang digunakan sebagai bahan semen memiliki dampak ekologi pada lingkungan, sedangkan kebutuhan semen semakin meningkat. Salah satu inovasi substitusi material beton adalah serbuk kaca karena memiliki potensi untuk menggantikan sebagian semen dengan kandungan silica (SiO2) yang cukup tinggi yaitu sekitar 70%. Penelitian bertujuan untuk mengetahui pengaruh substitusi serbuk kaca pada semen terhadap karakteristik beton segar dan kuat tekan pada beton Self Compacting Concrete (SCC). Penelitian dilaksanakan menggunakan metode eksperimen dengan pembandingan kuat tekan beton tiap variasi substitusi serbuk kaca terhadap semen, yaitu 0%, 8%, 9%, 10%, 11%, dan 12%. Untuk mendapatkan karakteristik beton SCC, ditambahkan admixture superplasticizer Visco-Crete 1003 sebesar 1,5% terhadap berat semen. Hasil penelitian menunjukkan beton SCC dengan substitusi serbuk kaca pada semen mengalami penurunan flowability, filling ability, dan passing ability. Beton SCC substitusi serbuk kaca umur 28 hari memiliki rata-rata kuat tekan berturut-turut dari variasi paling rendah adalah 35.71 MPa, 39.43 MPa, 41.08 MPa, 42.48 MPa, 41.55 MPa, dan 39.30 MPa. Hal tersebut menunjukkan persentase substitusi serbuk kaca sebesar 10% memiliki kuat tekan maksimum. Cement is used as main ingredient of aggregate binding component in concrete. Mining limestone which used as cement material has ecological impact on environment, while the need for cement is increasing. One of the concrete material substitution innovations is glass powder because the potential to replace some cement with fairly high silica (SiO2) content, namely around 70%. The research aims to determine the effect of glass powder substitution for cement on characteristics of fresh concrete and compressive strength of Self Compacting Concrete (SCC). The research carried out using experimental method by comparing compressive strength of concrete for each glass powder substitution variation, namely 0%, 8%, 9%, 10%, 11% and 12%. To obtain the characteristics of SCC concrete, superplasticizer admixture Visco-Crete 1003 was added at 1.5% the weight of cement. The research results showed that SCC concrete with substitution of glass powder for cement experienced a decrease in flowability, filling ability and passing ability. SCC concrete substituted with glass powder aged 28 days has an average compressive strength from the lowest variation, respectively, 35.71 MPa, 39.43 MPa, 41.08 MPa, 42.48 MPa, 41.55 MPa, and 39.30 MPa. This shows that glass powder substitution percentage of 10% has the maximum compressive strength.
