Srps En 13670 ((free)) -

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

The standard is the Serbian adoption of the European standard for the execution of concrete structures . It provides the technical requirements necessary to ensure that concrete structures are built according to the designer's intent, covering everything from site management to the final finish. Key Areas Covered by the Standard

Plastic, concrete, or steel spacers must be used to maintain the design concrete cover. This protects the steel from environmental corrosion. srps en 13670

SRPS EN 13670 applies to the execution of all permanent and temporary concrete structures. It provides common requirements to ensure that the completed structure meets the design assumptions made by engineers. What the Standard Covers

The assembly and connection of precast concrete parts on-site. Steel must be clean, free from loose rust,

Concrete must not segregate during transport or dropping into forms.

Use this standard to bridge design intent (Eurocode 2) and site practice: include clear execution specifications in contracts (concrete classes, cover, tolerances, curing), assign responsibilities, and maintain chain-of-custody documentation for materials and tests. Key Areas Covered by the Standard Plastic, concrete,

If no specific tolerance class is indicated in the project specification, Class 1 tolerances apply by default. Quality Management and Documentation

The design engineer must specify the Execution Class (typically ranging from Class 1 to Class 3) based on the structural risk, complexity, and consequences of failure:

Requirements for the design and construction of molds (formwork) and their supports (falsework). It ensures they are stiff enough to hold the weight of wet concrete and achieve the required surface finish.
