Abstract: This paper reviews the current state of knowledge regarding the deterioration mechanisms of concrete by agricultural effluents, mainly including liquid manure, silage juices and various effluents treated in biogas plant. This review first summarizes the biological and chemical compositions of agricultural effluents. The chemical composition in terms of aggressive components for the cementitious materials is mainly reported (organic acids, ammonium and CO2). In a second part, the main deterioration patterns of cementitious materials exposed to the effluents are reviewed by considering studies investigating (i) the chemical reactions of synthetic chemical compounds with the cementitious matrix, (ii) alteration mechanisms in presence of real effluents, (iii) the specific impact of the microbial biofilm. Missing information in the literature, flaws in the current concrete standards and identified challenges for further research are also pointed out here.
