Preventing segregation (separation of water, sand, and stone) during transit.

The production and quality of the raw concrete itself (this is covered by ). Health and safety regulations on-site. Contractual responsibilities between builders and owners. Practical Application

Must be applied uniformly and cannot be allowed to contaminate the reinforcement steel.

Execution of Concrete Structures: A Comprehensive Guide to SRPS EN 13670

If an execution falls outside specified tolerances, an engineering assessment must be carried out to determine if remedial actions (such as structural strengthening) are required. 7. Quality Management and Inspection

SRPS EN 13670 applies to the execution of both permanent and temporary concrete structures. It covers ordinary concrete, reinforced concrete, and prestressed concrete elements. Inclusions Buildings, bridges, tunnels, and civil engineering works. Cast-in-place (monolithic) concrete operations. Precast concrete element installation. Site-mixed and ready-mix concrete application. Exclusions

The standard defines strict tolerances for the positioning and dimensions of the structure, ensuring that the completed building matches the blueprints within acceptable margins. 4. Execution Classes (Execution Class - EXC) Contractual responsibilities between builders and owners

Do you need for a specific execution class (EXC2 vs EXC3)?

Used for simple, low-risk structures (e.g., single-story agricultural buildings).

This standard applies to both in-situ concrete works and the construction of precast concrete elements. It bridges the gap between design specifications and the final, completed structure, ensuring that safety and serviceability are maintained throughout the lifespan of the building.

Moderate risk, standard structures (e.g., standard multi-story buildings, routine infrastructure). Requires independent internal inspection. free from loose rust

Concrete should not be dropped from excessive heights to avoid air pockets and segregation.

Calibrating jacks and recording elongation data during stressing operations. Grouting ducts promptly to protect tendons from corrosion. 5. Concreting Operations: From Delivery to Curing

Steel must be clean, free from loose rust, oil, grease, or ice.
