Abstract
The use of chloride-based de-icers belongs to the most common road winter maintenance measures applied to prevent dangerous driving conditions. Chloride-based de-icers are the most frequently used worldwide. The essential difficulty with de-icers is their detrimental effect on concrete, other components of the road infrastructure and on vehicles. The interaction of various individual chloride salts with concrete is described in the paper; the experimental programme was focused on evaluation of the most frequently applied chloride-based de-icers in terms of damage to the air-entrained concrete used for highway construction. Three individual salts – NaCl, CaCl 2 , MgCl 2 – and one blend (NaCl + CaCl 2 ) were used. Their effect on concrete was investigated in terms of surface scaling during freezing-thawing cycles, residual mechanical properties and final ingress of chloride ions. Calcium chloride exhibited the most detrimental effect on the studied concrete.
期刊介绍：
The quarterly journal Roads and Bridges – Drogi i Mosty is published by the Road and Bridge Research Institute since September 2012 as a bilingual English-Polish journal. From 2002 to 2012 the journal was printed under the title Drogi i Mosty. The journal mission is to promote current achievements in science and technology in the field of road and bridge engineering. The journal is intended as a forum of the exchange of innovative concepts and solutions between the researches from different countries. Original scientific and technical papers in the field of civil engineering and related engineering sciences are published. The scope of Roads and Bridges – Drogi i Mosty includes design, construction, maintenance and safe use of roads, bridges, airports and other transportation structures.
