Product Description

POLYBIT® Polycrete 3D is a high-performance product that is specially formulated by blending OPC with non-shrinking additives, fibers, polymers and graded aggregates for a thixotropic consistency grout specifically for use with 3D construction printers. It offers excellent buildability, high early and final strength, and controlled consistency, making it ideal for automated layer-by-layer deposition in construction environments.

Ready to use dry mix requiring only water.
Optimized for 3D printing nozzle systems.
High thixotropy ensures shape retention during printing.
High early and final mechanical strengths.
Low shrinkage and cracking tendency
Consistent rheology for automated equipment.

How to Use

Surface preparation

Ensure the printing surface or interface is clean, roughened if required, and free from dust, oil, and contaminants. Base layers should be pre-wetted if needed, but free of standing water before application.

Mixing

Use a high-shear mechanical mixer. Gradually add 14.5 - 16.5% clean water (approx. 3.6 - 4.1L per 25 kg bag)into the mixer and slowly add the powder while mixing continuously. Mix for 3–5 minutes until a homogenous, lump-free, printable consistency is achieved. Do not add extra water once the mix has started to set.

Application

Apply using a compatible 3D construction printer system.The material is designed for extrusion through standard nozzles and provides excellent buildability without formwork. Recommended layer thickness is 10–50 mm. Ensure continuous feed for optimal bonding betweenlayers.
