Toward an accelerated biodeterioration test to understand the behavior of Portland and calcium aluminate cementitious materials in sewer networks

► This paper focuses on the biodeterioration of cementitious materials in sewer network. ► Calcium aluminate performs better than Portland mortars. ► Analyses reveal that CAC materials inhibit the growth of bacterial strains. ► Aluminum may be one of the responses of the good durability of CAC materials. ► An accelerated test is defined.
