Assessment of in-situ compressive strength in structures and precast concrete components
SIST EN 13791:2019

(1) This document:
- gives methods and procedures for the estimation of the in situ compressive strength and characteristic in situ compressive strength of concrete in structures and precast concrete components using direct methods (core testing) and indirect methods, e.g. ultra-sonic pulse velocity, rebound number;
NOTE    To align with the design standard EN 1992-1-1, where the compressive strength is based on 2:1 cylinders, the in situ compressive strength is based in 2:1 cores of diameter ≥ 75 mm.
- provides principles and guidance for establishing the relationships between test results from indirect test methods and the in situ compressive strength;
- provides procedures and guidance for assessing the conformity with the compressive strength class of concrete supplied to structures under construction where standard tests indicate doubt or where the quality of execution is in doubt.
(2) This document provides requirements for determining the in situ strength at test locations and the characteristic strength of test regions, but how this information is to be applied needs to be considered in the light of the specific situation and engineering judgement applied to the specific case.
(3) This document does not include the assessment of the quality of concrete for properties other than compressive strength, e.g. durability-related properties.
(4) This document is not for the assessment of conformity of concrete compressive strength in accordance with EN 206 or EN 13369, except as indicated in EN 206:2013+A1:2016, 5.5.1.2 or 8.4.
(5) This document does not cover the procedures or criteria for the routine conformity control of precast concrete components using either direct or indirect measurements of the in situ strength.
(3) This document does not include the assessment of the quality of concrete for properties other than compressive strength, e.g. durability-related properties.
(4)   This document is not for the assessment of conformity of concrete compressive strength in accordance with EN 206 or EN 13369, except as indicated in EN 206:2013+A1:2016, 5.5.1.2 or 8.4.

Products and systems for the protection and repair of concrete structures - Definitions, requirements, quality control and evaluation of conformity - Part 5: Concrete injection
SIST EN 1504-5:2013

This European Standard specifies requirements and conformity criteria for the identification, performance (including durability aspects) and safety of injection products for the repair and protection of concrete structures, used for:
-   force transmitting filling of cracks, voids and interstices in concrete (category F, see 3.1);
-   ductile filling of cracks, voids and interstices in concrete (category D, see 3.1);
-   swelling fitted filling of cracks, voids and interstices in concrete (category S, see 3.1).
The performance requirements in this part of this document may not be applicable to highly specialised applications in extreme environmental conditions, e.g. cryogenic use, nor do they cover specialised circumstances such as accidental impact, e.g. due to traffic or ice, or earthquake loading, where specific performance requirements will apply.
This European Standard does not cover:
-   the treatment of cracks by widening them and sealing them with an elastomeric sealing compound;
-   external filling of cavities, that is, the placement of product outside the structure (generally within the surrounding foundation soils, or at the interface between the structure and the soil); this is covered by EN 12715 [2], under contact grouting;
-   preliminary injection works, if necessary, to temporarily stop water passage during waterproofing injection.

c)   special technologies/innovative designs.
(5)   This standard does not apply to concrete members used only as equipment or construction aids for the execution.

EN 1504-9:2008(Main)
Products and systems for the protection and repair of concrete structures - Definitions, requirements, quality control and evaluation of conformity - Part 9: General principles for the use of products and systems
SIST EN 1504-9:2008

This Part of EN 1504 sets out basic considerations for specification of protection and repair of reinforced and unreinforced concrete structures (including, for example, pavements, runways, floor slabs and pre-stressed structures) using products and systems specified in other Parts of the EN 1504 series or any other relevant European Standard or European Technical Approval. This European Standard covers atmospherically exposed, buried and submerged structures.
This European Standard includes:
a)   the need for inspection, testing and assessment before and after repair;
b)   protection from causes of defects and their repair in concrete structures. Causes of such defects may include:
1)   mechanical actions, e.g. impact, overloading, movement caused by settlement, blast, vibration and seismic actions;
2)   chemical and biological actions from environments, e.g. sulphate attack, alkali aggregate reaction;
3)   physical actions, e.g. freeze-thaw, thermal cracking, moisture movement, salt crystallisation and erosion;
4)   fire damage;
5)   reinforcement corrosion resulting from:
i)   physical loss of the protective concrete cover;
ii)   chemical loss of alkalinity in the protective concrete cover as a result of reaction with atmospheric carbon dioxide (carbonation);
iii)   chloride (or other chemical) contamination of the concrete;
iv)   stray electrical currents conducted or induced in the reinforcement from neighbouring electrical installations.
c)   repair of defects caused by inadequate design, specification or construction or use of unsuitable construction materials;
d)   providing the required structural capacity by:
1)   replacement or addition of embedded or external reinforcement;
2)   filling of cracks and voids within or between elements to ensure structural continuity;
3)   replacement or addition of concrete or whole elements;
e)   waterproofing as an integral part of protection and repair;
