Abstract: Radar images can be employed to examine features of the ice surface and to determine ice drift. In the winter of 2012–2013, sea ice drift in the Bohai Sea was monitored using a marine radar system installed on an offshore ...

Abstract: Two novel polymeric cationic asphalt emulsifiers modified respectively by polyoxyethylene ether [named as polyether-type cationic asphalt emulsifier (PEAE)] and polystyrene [named as polystyrene-type cationic asphalt ...

Abstract: Polycarboxylate superplasticizers (PCEs) have been extensively used in the areas of construction and building; however, the application limitation of PCEs has emerged owing to their sensitivity to clay. In this work, three ...

Abstract: Comblike polycarboxylate superplasticizers (PCs) have been widely used as construction and building materials by means of high fluidity and fine dispersibility via electrostatic repulsion and steric hindrance. The conventional ...
