Cold Weather Masonry Construction - America's Cement ...

Mortar – Ideal temperatures for the placement and curing of masonry mortar is the range of 70°F + 10°F. In cold weather (40 degrees Fahrenheit and below) mortar materials need to be heated, otherwise the mortar is likely to exhibit slower setting times and lower early strengths.

Electric curing parameters of mortar and its mechanical ...

Concreting is not possible during cold weather due to the fact that fresh concrete is vulnerable to frost damage. Electric curing has the potential to prevent frost damage of mortar/concrete applied during cold weather. In this investigation, fresh mortar was exposed to −10 °C for 12 h to simulate freezing conditions during curing.
