FINITE ELEMENT ANALYSIS OF COLD EMBEDMENTS IN FRESH CONCRETE

This study evaluated the effects of steel embedments at subfreezing temperatures in fresh cocnrete, specifically, concrete poured around reinforcing steel initially at subfreezing ambient temperatures. The study was performed within the framework of the American Concrete Institute standards for cold weather concreting, so establishing the effects of cold embedments on fresh concrete and evaluating whether these precautions are adequate to prevent localized freezing. The details of the study are described, and the results are discussed. The finite element anslysis showed ice to form on cold embedments except when ambient temperatures were only slightly below freezing. Global conditions (mass of concrete, proximity of boundary contions, etc), it was found, had negligible effect on the transient freezing at the surface of the embedment.
