Lightweight ceramsite concrete used as an additional protection of fuel oil tanks on ships

Introduction of the semi-elastic barrier into ship fuel tanks requires of use of core material which will play role of carrier for elastic, fuel resistant layer. Such core material should be ligth, non reactive with water and fuel, fire resistant, corrosion neutral and finally easy applicable and relatively cheap. In paper the different problems like components, preparation, application as well as surface treatment for using of the light concrete as core material are presented.
