Tests of Selected Insulating Materials for Mass Concrete

摘要

During the early ages of mass concrete construction, the interior of the concrete mass can be at temperatures well above freezing while the bulkhead and lift surfaces are being subjected to sub-freezing temperatures. This condition can result in thermal cracking of the concrete in mass structures. The purpose of the program was to investigate various types of materials available for insulating mass concrete. Several of the most promising materials were selected for laboratory tests. The physical and thermal properties of these selected materials were determined. (Author)
