Six exact cements / one clear pricing path
Start with the strength your buyer recognizes: 42.5 or 52.5. Then compare the cement family, published result, pack formats, and exact designation to put on your pricing request.
Start with strength
The CBCM cement range
Choose the strength range, compare each product’s commercial case and published results, and take the exact designation into named-port pricing.
42.5 strength
Compare rapid-strength CEM II/A-M 42.5 R, sulfate-resistant CEM I 42.5 N-SR 5, and ASTM C595 Type IS (20). Type IS keeps its full ASTM designation and joins this buying range through its published 44.1 MPa 28-day result.
