Coatings with anti-icing performance possess hydrophobicity and low ice adhesion strength which delay ice formation and make ice removal easier. In this paper the anti-icing performance of nano/microsilica particle-filled amino-terminated PDMS (A-PDMS)-modified epoxy coatings was investigated. In the process the influence of the addition of A-PDMS on the hydrophobicity and ice adhesion

Surface protection has been accepted as an effective way to improve the durability of concrete. In this study nanosilica (NS) was used to improve the impermeability of cement-fly ash system and this kind of material was expected to be applied as surface protection material (SPM) for concrete. Binders composed of 70 cement and 30 #x0025 fly ash (FA) were designed and nanosilica (NS
