Add Grout 200 is an admixture for cementitious grouts, concrete and cementitious plaster where a reduced water/cement ratio and positive expansion is required. Applications include bed grouting, duct grouting, non-shrink infilling, high quality cementitious plaster and jointing.
Add Grout 200 is supplied as a powder admixture. The material is a combination of a plasticising agent and a gas-producing expansion medium. The plasticising agent allows the use of a reduced water/cement ratio with consequent increased strength and durability. The expansive medium counteracts the natural settlement and plastic shrinkage of the grout and aids stability and cohesion. Sufficient restrained expansion is developed to ensure a high degree of interfacial contact.
