Pumping - effects of weather extremes

The ambiant temperature has an effect on concrete pumping operations.

Hot Weather:
Since concrete sets faster in hot weather, a slow or intermittent pumping rate is necessary if delays in placement are anticipated. Also, wet burlap can be wrapped around pipelines to cool the concrete by evaporation.

Cold Weather:
During cold weather, concrete is in danger of freezing in exposed lines. Exposed lines should be run through enclosures or wrapped in insulation to prevent freezing.
