Cementitious binder materials (grout, mortar, concrete) are widely used for conditioning and disposal of low- and intermediate-level waste: as a waste encapsulation matrix, as grout for immobilizing waste in drums or as the waste container itself (Neilson and Dole, 1986; Frizon and Cau-dit-Coumes, 2006).These materials are thus subjected to a wide …

A paint binder is the substance that holds the paint together. Just like one would use cement as a binding agent to create concrete to build houses. Or how a chef would use eggs — which have highly elastic proteins that create a web that holds other ingredients together — to coat their meat before dipping it into flour for frying.
