thermal insulation: concrete measures in mixing as early as the agent of the strength of concrete conditions under control, before reaching 30 per cent are not subject to freezing. That is not subject to freeze around 12 hours.

Heat preservation measure: The concrete in mixes adds the early strength agent under the condition, the control concrete intensity achieved 30% before is not frozen.Also is about 12 hours is not frozen.

Insulation measures: adding early-strength admixture of concrete conditions, control of concrete strength achieved prior to 30% from the cold. Which is 12 hours or so from the cold.
