The temperature dependence on the strength development was investigated for the mixing design and the quality control of concrete containing antifreezing admixtures. The strength development of antifreezing concrete could be described by gompertz curve using maturity function as well as that of ordinary concrete. Antifreezing admixtures accelerated the strength development and increased the long term strength. Therefore, the correction value for concrete strength in terms of outdoor air temperature designated in JASS 5 would be decreased. However, on freezing condition, the strength development was delayed even when using antifreezing admixtures. The datum temperature of maturity function was not necessarily lowered by using antifreezing admixtures. It was currently recommended admirable to be -10°C used for practical use. The temperature tracing curing was useful for the quality control and the decrease of the term of works.
