dc.description.abstractSelf Compacting Geopolymer Concrete (SCGC) berbasis fly ash merupakan alternatif beton ramah lingkungan yang berpotensi mengurangi penggunaan semen Portland. Namun, pencapaian karakteristik Self Compacting Concrete (SCC) pada beton geopolimer masih menjadi tantangan, terutama pada aspek workability. Penelitian ini bertujuan menganalisis workability, kuat tekan, kualitas air limbah, dan carbon footprint SCGC dengan variasi molaritas NaOH 8 M, 10 M, dan 12 M serta rasio NaOH terhadap Na2SiO3 sebesar 1:1,5. Hasil penelitian menunjukkan bahwa seluruh variasi SCGC belum memenuhi kriteria SCC berdasarkan EFNARC 2005 karena nilai slump flow belum mencapai rentang yang dipersyaratkan sehingga pengujian L-Box dan V-Funnel tidak dilanjutkan. SCGC 12 M dengan curing suhu ruang menghasilkan kuat tekan tertinggi sebesar 35,39 MPa pada umur 28 hari, sedangkan curing suhu tinggi mempercepat pencapaian kuat tekan optimum yang awalnya 28 hari menjadi umur 7 hari sebesar 29,18 MPa. Dibandingkan beton normal, SCGC menghasilkan kualitas air limbah yang lebih baik pada beberapa parameter dan mampu menurunkan emisi CO2 sebesar 43,44%, sehingga berpotensi mendukung penerapan konstruksi berkelanjutan
dc.description.abstractSelf-Compacting Geopolymer Concrete (SCGC) based on fly ash is a sustainable alternative to conventional concrete, although achieving adequate workability remains challenging. This study evaluated the workability, compressive strength, wastewater quality, and carbon footprint of SCGC using NaOH molarities of 8 M, 10 M, and 12 M with a NaOH-to-Na2SiO3 ratio of 1:1.5. The results showed that all SCGC mixtures failed to satisfy the EFNARC (2005) criteria because the slump flow values were below the required range, preventing further L-Box and V-Funnel tests. The 12 M mixture under ambient curing achieved the highest 28-day compressive strength of 35.39 MPa, while heat curing accelerated strength development to 29.18 MPa at 7 days. Compared with conventional concrete, SCGC produced wastewater with better environmental performance in several parameters and reduced CO2 emissions by 43.44%. These findings demonstrate the potential of fly ash-based SCGC as a more sustainable construction material, although further improvement in workability is still required.
