常见问题
•Can precast elements be produced to my project drawings?
Yes. Russian precast plants regularly cast non-catalogue items — drainage channels, foundation blocks, manhole rings and covers — against customer drawings. You provide dimensioned drawings and concrete class requirements; the plant returns a mould cost, unit price and production schedule. Tooling for a new shape typically takes 2–4 weeks before serial casting begins.
•How do Russian cement and concrete grades map to EN 197 and EN 206?
Russian cement is classified under GOST 31108, which mirrors the EN 197-1 system, so CEM I 42.5 has a direct domestic equivalent. Concrete strength classes B25 or B30 convert to roughly C20/25 and C25/30. Suppliers provide conversion tables and mill certificates so your engineers can verify equivalence before approval.
•Is exporting cement itself practical, or only products made from it?
Bagged cement is exported, but freight economics matter: it normally makes sense by rail to neighbouring EAEU and Central Asian markets, or by sea in big-bags from Black Sea ports for orders of 1,000 tonnes and up. For smaller volumes, dry mixes and admixtures usually offer better margin per container.
•What documentation accompanies concrete admixtures?
Each admixture ships with a technical data sheet stating dosage range and effect, a safety data sheet, batch quality certificate and EAC conformity documentation. Manufacturers also provide trial protocols and recommended mix designs, and most will supply 20–50 kg test quantities so your ready-mix plant can run its own verification batches.
•How is brick protected from transit damage on long routes?
Export brick is shrink-wrapped on pallets with corner protection and strapping rated for double handling. Contracts normally allow a breakage tolerance of around 2 percent for sea or combined transport. For long rail hauls, plants load directly into wagons with dunnage, which keeps damage rates lower than containerised double handling.
