Cold Concrete is Portland cement concrete that is placed and cured at ambient temperatures below 32 degs F (0 degs C) without temporary protection or additional heating. Special admixtures are used to depress the freezing point and to allow strength build-up without detrimental effects to the concrete. A survey of Scandinavian cold concrete was conducted. An extensive literature search resulted in a listing of 31 references. A data base was designed to provide a basis for compiling available data on material properties and costs. From several sources, data were gathered on mix components, 'anti-freeze' admixtures and their proportions, water/cement ratios, curing temperatures and associated compressive strengths. The elements of an expert system were designed and demonstrated; when fully developed, this system will allow the designer, contractor and/or owner to select the optimum mix for a given set of environmental and use conditions.
