SikaGrout®-234

Shrinkage-compensated, high-performance sealing and wedging mortar – reduced environmental impact Product Description SikaGrout®-234 is a ready-to-use hydraulic mortar with compensated shrinkage, designed for the sealing and bracing of industrial and structural elements. After mixing with water, it forms a fluid and easy-to-apply mortar. It contains raw materials from recycling as a partial replacement for Portland cement, which significantly reduces the carbon footprint. The product complies with the NF EN 1504-6 standards for the anchoring of reinforcing bars and with the P 18-821 standard for wedging products based on hydraulic binders. The application thickness varies from 12 to 200 mm per pass depending on use. Areas of application Sealing anchor bolts or concrete bars Precision sealing of industrial equipment subjected to shock or vibration Sealing of railway rails or overhead cranes Timing of turbines, alternators, compressors, generators and machine tools Wedging of beams or bridge support constructions Keying of prefabricated metal, reinforced or prestressed concrete elements Suitable for environments XC1 to XC4, XD1 to XD3, XS1 to XS3, XF1 and XF3, XA1 to XA3 (EN 206) Features and Benefits Reduction of carbon footprint thanks to recycled raw materials Resistant to sea water and sulfate waters Free from chlorides and oxidizing metal particles Compensated shrinkage and low heat generation High mechanical resistance in compression and bending, even in the short term Excellent adhesion to concrete, mortar and steel Monolithic connection resistant to shocks and vibrations Resistant to variations in humidity and temperature; water and oil resistant Quick return to service thanks to high initial strengths Can be mixed with fillers for wedging and sealing of high thickness or volume (outside NF scope) Approvals and standards CE marking according to NF EN 1504-6: Anchoring of steel reinforcing bars Minutes of CNERIB DTEM tests 94/2022 Technical information Chemical basis: Portland cement, synthetic materials and additives Application thickness: 12 to 200 mm per pass Appearance / Color: Gray powder; after hardening: concrete gray mortar Packaging 25 kg bag Preservation 12 months in original, unopened packaging Storage conditions Store away from humidity Store in the original closed packaging
