<note>Meningkatnya kebutuhan akan infrastruktur berkelanjutan saat ini merupakan upaya untuk mencegah kerusakan lingkungan dari segi konstruksi bangunan. Kombinasi penggunaan material beton porous dan geopolimer untuk menggantikan material beton konvensional diharapkan menjadi solusi agar terciptanya infrastruktur berkelanjutan dan mencegah kerusakan pada lingkungan. Penelitian ini memiliki tujuan untuk memahami interaksi variasi ukuran agregat yang digunakan pada campuran beton porous geopolimer berbahan dasar fly ash terhadap nilai kuat tekan dan kemampuannya untuk mengalirkan air di struktur betonnya. Tiga ukuran agregat digunakan dengan ukuran 0,075-2,5 mm, agregat 2,5-5 mm, dan agregat 5-10 mm diteliti dalam empat variasi perbandingan yaitu, 25% : 45% : 30%, 20% : 48% : 32%, 15% : 51% : 34%, dan 10% : 54% : 36% yang diuji pada umur 7, 14, dan 28 hari. Hasil dari penelitian yang dilakukan, diperoleh nilai kuat tekan optimum pada variasi 4 dengan komposisi agregat 0,075-2,5 mm sebanyak 10% dengan nilai sebesar 9,02 MPa dan nilai koefisien permeabilitas sebesar 0,46 cm/detik.
