The goal of this research is to see how resistant concrete is to organic acid and abrasive corrosion, both of which are common in pig farms. Cement was substituted with fly ash and silica fume at various weight percentages up to 30% in the concrete compositions. The compressive strength and mass loss owing to organic acid corrosion of cubic mortar and concrete specimens were constructed and tested. The test findings showed that combining fly ash and silica fume greatly increased the concrete's compressive strength, especially over lengthy curing durations. The addition of fly ash and silica fume considerably increased the resistance of the concrete and mortar against organic acid corrosion
