CPJ 55 cement (Composite Portland Cement, strength class 52.5 MPa at 28 days, marketed as 55 MPa) is a high-performance cement reserved for demanding works. Its clinker-rich composition (≥ 70%) and high fineness (≥ 380 m²/kg Blaine) give it a compressive strength of 55 MPa at 28 days, ideal for civil engineering structures, infrastructure and coastal works.
Produced at the Dakhla Aménagement grinding plant in Dakhla, CPJ 55 complies with Moroccan standard NM 10.1.004 and European standard EN 197-1 (CEM II/A-L 52.5). Each batch is lab-tested before shipment: compressive strength, fineness, setting time, stability and sulfate resistance. Conformity certificates are systematically provided.
CPJ 55 advantages
- Compressive strength of 55 MPa at 28 days — high-performance concrete (C40/50 and beyond)
- Superior durability against chloride (sea salts) and sulfate attacks
- High fineness (≥ 380 m²/kg) — better hydration and early strengths
- Ideal for prestressing and heavy precasting (long spans, thin elements)
- Adapted to coastal areas (Dakhla, Boujdour, Laayoune) and maritime works
- Compliant with NM 10.1.004 / EN 197-1 — certifications available on request
Recommended CPJ 55 dosage
For high-performance concrete (C35/45), allow about 400 kg of CPJ 55 per m³. For highly stressed concretes (C40/50 and C45/55), plan for 420-450 kg/m³ with a low W/C ratio (≤ 0.45) and the possible use of superplasticizers. CPJ 55 is particularly suitable for prestressing thanks to its delayed initial setting (≥ 60 min) which facilitates placement. Our technical team can support you in formulating your concrete.
CPJ 55 price in Morocco
CPJ 55 price starts at 1,600 DH/T in bulk (minimum 30T), 1,650 DH/T in 50kg bags (1T pallet) and 1,680 DH/T in 1T big bag. The premium of about 100 DH/T over CPJ 45 reflects the higher strength and clinker-richer composition. For large civil engineering projects, volume discounts are negotiable.

Frequently asked questions about CPJ 55
When to use CPJ 55 cement rather than CPJ 45?⌄
CPJ 55 (55 MPa) is recommended as soon as the structure is highly stressed: major civil engineering works (bridges, viaducts), infrastructure (ports, airports, dams), prestressed elements, heavily loaded industrial slabs, and structures in coastal areas exposed to sea salts. For standard construction (residential buildings, masonry), CPJ 45 is sufficient and more economical.
What is the price of CPJ 55 cement in Morocco?⌄
Dakhla Aménagement CPJ 55 is available from 1,600 DH/T in bulk (tanker truck, min. 30T), 1,650 DH/T in 50kg bags (1T pallet) and 1,680 DH/T in 1T big bag. The premium over CPJ 45 reflects the higher strength (55 MPa vs 45 MPa). Volume discounts available.
Is CPJ 55 suitable for coastal zones?⌄
Yes, CPJ 55 is particularly suitable for coastal areas such as Dakhla, Boujdour or Laayoune. Its composition and high strength provide better durability against chloride (sea salts) and sulfate attacks. For highly exposed structures (bridge piers, marine works), we recommend an adapted dosage and additional protection.
What are the dosage and setting time of CPJ 55?⌄
CPJ 55 has an initial setting time ≥ 60 minutes and a fineness ≥ 380 m²/kg, making it ideal for high-performance concrete. Recommended dosage ranges from 400 kg/m³ (C35/45 concrete) to 450 kg/m³ (C40/50 concrete) depending on the exposure class and target performance. Consult our technical team for an optimized dosage.
