In agricultural construction, the most frequently used construction material is concrete. In particular swine farm, traditional concrete flooring system in the business is conventional concrete. However, the conventional concrete floor has several key issues on its surface. They are easily to be spalled and cracked, pig scour, rough areas, and low wear resistance of acid from animal feed. This research involves study in the ratio between Portland cement and supplementary materials (fly ash and silica fume) that is the most resistant to abrasion. Concrete samples were cured in water for 28 days, then submersed in lactic acid solution at 30 °C (pH 2-3). After exposure to the acid solution, every 7, 14, 28, and 56 days, the samples will be test for attrition on the face of concrete in accordance with ASTM C944 to simulate the acceleration reaction refer to animal behaviour and corrosion from acid of feed. From experiment, it was found that increasing the volume of fly ash and silica fume can increase concrete resistance to corrosion due to acid derived from feed.
