Content
Ice, snow and, frost create problems in many areas of construction. For example, when concrete is poured the ground must be thawed and free of snow and frost. In agriculture, planters often plant seeds, bulbs, and the like before the last freeze of the year. In such examples, it is necessary to keep the concrete, soil, and other surfaces free of ice, snow, and frost. In addition, curing of concrete requires that the ground, ambient air, and newly poured concrete maintain a temperature between about 50 degrees and about 90 degrees. In industrial applications, outdoor pipes and conduits often require heating or insulation to avoid damage caused by freezing. In residential applications, it is beneficial to keep driveways and walkways clear of snow and ice.
