MAPEGROUT THIXOTROPIC
Mapegrout Thixotropic r4 is a ready-mixed powdered mortar composed of high-strength cements, selected aggregates, special additives and synthetic fibres prepared according to a formula developed in the MAPEI Research & Development laboratories. When mixed with water, Mapegrout Thixotropic becomes an easily workable mortar with high thixotropic properties that can be applied on vertical surfaces without sagging even in great thicknesses and with no need for formwork. If is prepared by only adding water, it must be cured under damp conditions in order to guarantee that the product expansive properties develop completely and correctly. Unfortunately, it is not easy to guarantee that these conditions are created on site.
However, to guarantee that the expansive properties of Mapegrout Thixotropic are carried out in the open air, 0.25% of Mapecure SRA, a special additive which has the property of reducing both plastic and hydraulic shrinkage, may be used to great advantage when added to the mix. Mapecure SRA has a very important role to play, in guaranteeing better curing of mortar.
