Acid resistance and self-healing crack-sealing performance of Shewanella oneidensis-modified low-calcium fly ash geopolymer concrete

Abstract Durability of cementitious materials in sewer infrastructure is greatly affected by sulphuric acid attack and cracking. A low-calcium fly ash-based geopolymer concrete (GPC) enhanced with Shewanella oneidensis, a dissimilatory metal-reducing bacterium (DMRB), was tested...
