organic resin coatings such as epoxy, polystyrene and polyurethane have been used to protect concrete farm silos against chemical attack by silage juices, chiefly lactic and acetic acids this paper describes tests to evaluate some of these organic resin coatings. the paper further describes the development and test results of an improved, chemically resistant, portland cement-based mortar with an organic polymer and highly active pozzolanic admixtures. the addition of fibers improves the tensile strength and toughness of the mortar, permitting thin applications to seal new silo walls and to repair those previously damaged. study results are discussed.
