Fosroc Conbextra PM is a pre-blended thixotropic mortar designed for pump or hand application in a single pack format. Its thixotropic nature means it remains stable and workable d uring pumping but holds its position once placed, making it well suited to gap-filling in precast concrete where flowable grouts would be impractical. The pre-blended formulation eliminates site batching variations, and part packs can be mixed where smaller quantities are needed. Typical applications include, Structural grouting of gaps in precast units and high-strength pointing Benefits Various methods can be used for application. It can be applied by rotor stator or worm pump using 25mm ID hosing, or by pointing gun or trowel for hand application. No priming required Rapid strength gain Shrinkage compensated Good to know Minimum application thickness: 10mm Maximum grain size: 0.75mm Mix ratio: 3.1–3.3 litres water per 20kg bag Approximate yield: 10.5 litres per 20kg bag Do not use below +3°C Bags are not waterproof, store in dry conditions Compressive strength: 36 MPa at 1 day / 54 MPa at 7 days / 60 MPa at 28 days (w/p 0.16)not waterproof, store in dry conditions Material should be tooled or cut back to the required profile whilst still wet.
