DURABILITAS JANGKA PANJANG MORTAR 100% FLY ASH TIPE C DI LINGKUNGAN SULFAT

Kevin Guyana, Djwantoro Hardjito, Antoni Antoni

Abstract


Sejauh ini hampir belum ada penelitian tentang karakteristik dan durabilitas jangka panjang mortar dengan material pengikat 100% fly ash tipe C. Penelitian ini dilakukan untuk mengevaluasi kuat tekan dan sudut mortar 100% fly ash dan ketahanannya di lingkungan sulfat. Berdasarkan penelitian yang telah dilakukan, mortar dengan 100% fly ash memiliki ketahanan yang lebih baik dibandingkan dengan mortar 100% semen di lingkungan sulfat hingga waktu 365 hari. Selain itu mortar 100% fly ash memiliki kuat tekan yang cukup baik, sebesar 78,4% dari kuat tekan mortar 100% semen pada umur 365 hari. Lebih dari itu, penyusutan yang terjadi pada mortar 100% fly ash ternyata lebih kecil dari mortar dengan 100% semen.

Keywords


100% fly ash, sulphate resistance, mortar, boraks, kalsium hidroksida, kuat tekan, penyusutan.
