One sustainable product that has shown promise in concrete application is commercially available soybean oil emulsion marketed for concrete curing. This paper describes research performed to determine what impacts soybean oil had on concrete and to evaluate the effectiveness as a curing agent. Soybean oil was tested for moisture retention and evaluated surface applied and integrally mixed. Depth of penetration was measured using several application schemes to determine effectiveness in reducing surface permeability. Deicer testing was then performed on straight cement samples and samples with 50% replacement of Portland cement with blast furnace slag. Results indicate that soybean oil substantially reduces moisture loss from fresh concrete and provides greatly improved deicer scaling resistance. For projects looking for more sustainable curing options or those located in environmentally sensitive areas where traditional curing compounds are not allowed, soybean oil may be a viable alternative.
