How do temperature ranges of concrete under polyethylene film compare with concrete under waterproof paper?
Tests by the New York State Department of Public Works showed only slightly greater temperature range under white opaque 4-mil polyethylene sheeting than under waterproof paper. But the temperature range under clear polyethylene was significantly greater than under paper. On the other hand, cores taken from polyethylene cured pavements showed somewhat greater average compressive strengths than cores taken from paper cured concrete.
