Abstract:
In winter, heaters are used to prevent concrete from freezing and to assure an acceptable strength before form removal and ongoing construction. Typically, cylindrical forced air heaters, that are generally large and few in number, are used for this process. Experiments were carried out at three sites to compare the results of traditional heating procedures and a new method for curing concrete using high-efficiency infrared natural gas heaters. The new infrared heating system used a greater number of smaller heaters to transfer heat to the slab of concrete.
