Cold Weather Requirements (LCUASS 22.3.7 G)
Prior to placing concrete, ice, snow and frost shall be removed from the forms and
subgrade. In no case shall concrete be placed against frozen ground or against ground
containing frost. Except by specific written authorization, concrete shall not be placed
unless the air temperature adjacent to the concrete placement is 30°F and rising and
placing shall cease when the air temperature adjacent to the concrete placement falls
below 40°F as determined by the Local Entity Engineer. When concrete placement is
permitted during cold weather, the temperature of the mix shall not be less than 50°F
nor more than 90°F at the time of placement. Aggregates or water shall not be heated
to a temperature exceeding 150°F. Materials containing frost or lumps of frozen
material shall not be used. If heated mixing water and/or an accelerator are used, the
above limits may be waived only with written permission of the Local Entity
Engineer. When concrete is placed in cold weather and the air temperature is
expected to drop below 35°F, a suitable blanketing material shall be at the job site
during placement. At any other time when the air temperature is expected to reach the
freezing point for a period of 72 hours after placement, the work shall be blanketed
for protection of the concrete.
