Effect of Cold Temperature on the Chloride-Binding Capacity of Cement

D. K. Panesar and S. E. Chidiac
Service life of reinforced concrete structures exposed to chloride ions is closely related to the rate of chloride ion diffusion through the concrete. The determination of the apparent chloride diffusion coefficient of concrete takes into account the chloride-binding capacity but not the effect of t ... [J. Cold Reg.

A Holistic Approach to Decision Making in the Formulation and Selection of Anti-Icing Products

Xianming Shi and Michelle Akin
To effectively fight snow storms in the challenging funding environment, many maintenance agencies in North America have started to produce their own anti-icing liquids, instead of procuring commercial anti-icers. This work demonstrates a systematic approach to collaborative, data-driven and multi-c ... [Journal of Cold Regions Engineering doi:10.1061/(ASCE)CR.1943-5495.0000039] posted Thu Sep 22, 2011.

Experimental Study on Carbon Fiber Tape Based Deicing Technology

Ting Yang, Zhaohui Joey Yang, Mithun Singla, Gangbing Song, and Qiang Li
In cold regions, snow and ice cause serious safety problems to the transportation system. South central Alaska, particularly Anchorage, is susceptible to a number of icing events due to frequent freeze/thaw cycles in the winter season. Traditionally, deicing has been accomplished by mechanical, chem ... [Journal of Cold Regions Engineering doi:10.1061/(ASCE)CR.1943-5495.0000038] posted Sat Sep 17, 2011.
