The goal of this project was to develop a chemical admixture that would reduce the need for wintertime thermal protection of freshly placed concrete. Chemicals were investigated for their ability to promote strength gain in concrete cured below 0 deg C. The project was carried out in five phases. Phase 1 evaluated existing and new admixtures. Phase 2 measured the effect of promising chemicals on concrete properties. Phases 3 and 4 tested the practicality of using the new technology/admixture in the field. Phase 5 disseminated the findings through an Army conference and through the development of this report, in addition to normal W.R. Grace advertising channels. Laboratory strength tests established that two prototype admixtures were capable of protecting concrete down to -5 deg C. Results from other laboratory tests show that the chemicals pose no harm to the concrete or embedded ferrous metals. Concrete containing the prototype admixtures passes standard freeze-thaw tests, does not shrink unusually, does not contain harmful alkalis, and does not produce irregular hydration products. Field tests clearly demonstrated that working with these new admixtures requires no new skills. The concrete can be mixed at lower temperatures, saving energy. The admixtures are easily dosed into the mixing trucks, as is normal practice today, and concrete is finished in the usual manner. Estimates show that the two prototype admixtures can extend the construction season by as much as three months in the contiguous United States. The prototype has proved that low-temperature admixtures are possible. The industry partner sees the need to develop admixtures that will work to -10 deg C before going commercial with this technology.

During the performance of concreting tasks in the winter of 1971-72, in the construction of facilities in the Kakhovskaya irrigation system and the Northern Crimean Canal, antifreeze admixtures were introduced, assuring the necessary conditions for its hardening at negative temperatures. The introduction into concrete, of both the combined and the single component antifreeze admixture promotes an appreciable prolonged improvement in the convenient pouring quality of the concrete mixture. The use use of concrete with antifreeze admixtures made it possible to eliminate the seasonal nature in performing concrete operations and to lower the cost of pouring one cubic meter of concrete by 3.5 rubles as compared with the pouring methods involving heating.
