DEFINITION
Novo PT Add- Grout is supplied as a powder additive for cementations grouts and concrete. The material is a combination of a high selective polymer for producing expansion medium and high follow ability for grout and concrete.
USES
Novo PT add-Grout is specially formulated as post tension for precast cables ducts, also used as an additive for cementations grout; where a low water/cement ratio and positive expansion are required. Application includes bed grouting, duct grouting, no shrink infilling and jointing.
ADVANTAGES
 Shrinkage compensation expansion system compensates for plastic shrinkage.
 Durability Reduced water/cement ratio ensures low permeability.
 Flow ability gives high grout fluidity with low water/ cement ratio.
 Chloride-free no chloride content.
PERFORMANCE SPECIFICATION
All grouting (specify details and areas of application) must be carried out with a cement-based grout incorporating a plasticized, expanding powder admixture. The admixture must be iron-free, chloride-free and shall provide an expansion of 1- 4% in the plastic grout, by means of a gaseous system
