Abstrak

Penambahan arang aktif ke dalam matriks semen dapat meningkatkan kepadatan mortar, dan daya tahan mortar. Tujuan dari penelitian ini adalah menganalisa pengaruh arang aktif terhadap karakteristik mortar komposit meliputi kuat tekan, densitas dan daya serap air. Pembuatan mortar komposit dengan komposisi arang aktif terhadap berat semen (1%, 2%, 3%, 4%, dan 5%), perbandingan semen dan pasir adalah 1:3. Komposisi tersebut akan diuji dan dianalisa pengaruhnya terhadap kuat tekan, densitas dan daya serap air mortar komposit. Hasil penelitian menunjukkan penambahan arang aktif tidak berpengaruh signifikan terhadap karakteristik mortar komposit, kecuali pada densitas setting. Penambahan arang aktif sebesar 5% menunjukkan komposisi optimal dengan nilai kuat tekan 11,67 MPa, densitas setting 2092,91 kg/m3, densitas oven dry 1853,93 kg/m3, dan daya serap air 15,20%.
