BETON BERPORI DENGAN VARIASI UKURAN AGREGAT KASAR

Dahlia Patah, Amry Dasar

Abstract


Ukuran agregat merupakan faktor penting yang mempengaruhi kuat tekan beton berpori. Penelitian ini berfokus pada hubungan antara ukuran agregat, kuat tekan, struktur pori, permeabilitas dan kemudian memahami pengaruh ukuran agregat terhadap kuat tekan beton berpori. Sebanyak tiga ukuran agregat kasar 5-10 mm, 10-20 mm dan 20-30 mm disiapkan. Pada penelitian ini dibuat dua variasi kombinasi agregat kasar. Variasi 1 untuk kombinasi agregat kasar ukuran 5–10 mm dan 10–20 mm. Variasi 2 untuk kombinasi ukuran agregat kasar 20–30 mm dan 10–20 mm. Untuk setiap variasi dengan kombinasi pencampuran 100%:0%, 75%:25%, 50%:50%, 25%:75%, dan 0%:100%. Metode yang digunakan adalah pengujian kuat tekan, porositas, dan permeabilitas. Hasil pengujian menunjukkan bahwa kuat tekan komposisi 50%:50% pada Variasi 1 meningkat pesat dengan ukuran agregat 10-20mm dan 5-10mm dengan nilai 22,40 MPa yang memenuhi persyaratan minimum yang ditentukan oleh Standar Nasional Indonesia yaitu Kelas B (aplikasi taman parkir). Sedangkan penggunaan agregat ukuran 100% seragam memiliki kuat tekan yang rendah.
