Reinforced Concrete: Techniques and Best Practices in Morocco

Reinforced concrete is the most widely used construction material in Morocco, combining the compressive strength of concrete and the tensile strength of steel. In Moroccan climatic conditions, characterized by high temperatures and strong evaporation, the implementation of reinforced concrete requires special precautions to guarantee the quality of the structures.

Reinforcement must be dimensioned according to Moroccan seismic regulations (RPS 2011), particularly in the country's seismic zones. The concrete cover of the reinforcement, that is, the minimum distance between the steel surface and the concrete surface, must be at least 3 cm in standard environments and 5 cm in marine or aggressive environments. This cover protects the steel against corrosion.

Pouring concrete in hot climates requires increased vigilance. The temperature of fresh concrete should not exceed 30°C to avoid too rapid setting. It is recommended to pour early in the morning or late afternoon, to moisten the formwork before pouring, and to protect the fresh concrete from sun and wind. Curing, which consists of keeping the concrete moist for at least 7 days, is essential to achieve the specified strengths.

For projects in Morocco, the choice of cement is crucial. Dakhla Aménagement's CPJ 45 is perfectly suited for standard reinforced concrete structures, while CPJ 55 is recommended for heavily loaded elements and structures in marine environments.
