A NEW CEMENT FOR COLD WEATHER CONSTRUCTION

The results of the investigation indicate that concrete containing regulated-set cement will gain strength even when unprotected when placed at temperatures as low as 15 F. This is accomplished because the chemical reaction between the cement and water is accelerated and hydration heat is generated almost immediately after mixing of the cement and water. This heat generation sustains temperatures within the mixture above freezing long enough for considerable strength buildup. The significance of this is that with the use of regulated-set cement the implementation of normal protection measures for concrete placed in cold weather can be delayed both at the start and finish of the winter season and that the period of initial concrete protection can be reduced during any winter concrete placements. In all these instances, this should result in substantial cost savings and reductions in energy requirements normally used in concrete heating.
