Abstrak

Konstruksi ramah lingkungan pengembangan bahan bangunan berkelanjutan dan ekonomis. Geopolimer semakin banyak diminati, dengan memanfaatkan limbah. Bahan sisa limbah yang sebagian besar mengandung silikon (Si) dan Aluminium (Al) merupakan bahan sumber pembuatan geopolimer. Geopolimer adalah komposit polimer buatan yang merupakan produk berkelanjutan ramah lingkungan. Fly ash sebagai pengikat pada geopolimer karakteristik fisik dan kimianya yang membantu terjadinya reaksi geopolimerisasi. Kandungan alumino silikat dalam jumlah tinggi dalam alkalin. Konstruksi bahan bangunan berkelanjutan menggabungkan limbah industri dan pertanian dalam bentuk karbon aktif cangkang kelapa sawit. Penggunaan bahan limbah memecahkan masalah pembuangan limbah dan meminimalkan permintaan sumberdaya alam untuk pembuatan mortar. Penelitian ini menghasilkan mortar geopolymer dengan menggunakan fly ash pengganti semen dan karbon aktif cangkang kelapa sawit pengganti pasir.
