This document specifies the method for the determination of the secant modulus of elasticity in compression of hardened concrete on test specimens which can be cast or taken from a structure. The test method allows the determination of two secant moduli of elasticity: the initial modulus, EC,0 measured at first loading and the stabilized modulus, EC,S measured after three loading cycles. Two different test methods are given. The first (Method A) is for determination of both initial and stabilized moduli, the second (Method B) is for determination of stabilized modulus only.

This document specifies a method for determining the rebound number of an area of hardened concrete using a spring-driven hammer. NOTE 1 The rebound number determined by this method can be used to assess the uniformity of concrete in situ, to delineate zones or areas of poor quality or deteriorated concrete in structures. NOTE 2 The test method is not intended as an alternative for the compressive strength determination of concrete (EN 12390-3), but with suitable correlation, it can provide an estimate of in situ compressive strength. For the assessment of in-situ compressive strength, see EN 13791. NOTE 3 The hammer can be used for comparative testing, referenced against a concrete with known strength or against a concrete which has been shown that it has come from a defined volume of concrete with a population verified as conforming to a particular strength class.

(1) The basis for the design of building and civil engineering works in masonry is given in this Part 1-1 of EN 1996, which deals with unreinforced masonry, reinforced masonry and confined masonry. Principles for the design of prestressed masonry are also given. This Part 1-1 of EN 1996 is not valid for masonry elements with a plan area of less than 0,04 m2. (2) For those types of structures not covered entirely, for new structural uses for established materials, for new materials, or where actions and other influences outside normal experience have to be resisted, the provisions given in this Part 1-1 of EN 1996 may be applicable, but may need to be supplemented. (3) Part 1-1 of EN 1996 gives detailed rules which are mainly applicable to ordinary buildings. The applicability of these rules may be limited, for practical reasons or due to simplifications; any limits of applicability are given in the text where necessary. (4) Part 1-1 of EN 1996 does not cover: — resistance to fire (which is dealt with in EN 1996-1-2); — particular aspects of special types of building (for example, dynamic effects on tall buildings); — particular aspects of special types of civil engineering works (such as masonry bridges, dams, chimneys or liquid-retaining structures); — particular aspects of special types of structures (such as arches or domes); — masonry where gypsum, with or without cement, mortars are used; — masonry where the units are not laid in a regular pattern of courses (rubble masonry); — masonry reinforced with other materials than steel.

This document specifies a procedure for carrying out impressed current electrochemical chloride extraction from chloride bearing concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement and/or post-tensioned tendon ducts embedded in concrete. In the latter case, it is essential to verify that there is no risk of hydrogen embrittlement, if necessary by conducting trials and installing monitoring during the treatment. This document does not apply to concrete containing pre-stressing steel which can suffer hydrogen embrittlement during chloride extraction, or to concrete containing epoxy-coated or galvanized reinforcement. In case of post-tensioned, pre-stressing concrete, the endangered tendon strands may be shielded by the tendon ducts from unwanted and/ or exceeded polarization into the cathodic range and respective water reduction.

This document specifies a method for determining the adhesion of a bituminous emulsion coated onto aggregate when immersed in water. The method considers two different aspects of adhesivity, i.e. immediate adhesivity and water effect on binder adhesion. The method may be used with a reference aggregate. In that case, it measures the intrinsic adhesion behaviour of a bituminous emulsion. The method may also be used with a specific aggregate as used on a job site. WARNING -The use of this document may involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

This document provides principles and requirements for the assessment of environmental, social and economic performance of buildings and civil engineering works taking into account their technical characteristics and functionality. Assessments of environmental, social and economic performance are the three aspects of sustainability assessment of buildings and civil engineering works, or combination thereof, (hereafter referred to as “construction works”). The framework applies to all types of construction works, both new and existing, and it is relevant for the assessment of the environmental, social and economic performance of new construction works over their entire life cycle, and of existing construction works over their remaining service life and end of life stage. The sustainability assessment of construction works concentrates on the assessment of environmental, social and economic aspects and impacts of construction works expressed with quantifiable indicators. It includes the assessment of a construction works’ influence on the environmental, social and economic aspects and impacts on the local area (area of influence) and of the local infrastructure beyond the curtilage of the building and the civil engineering works. It excludes environmental, social and economic risk assessment. The European Standards developed under this framework do not set the rules for how the different assessment methodologies may provide valuation methods; nor do they prescribe levels orclasses for measuring performance. NOTE Valuation methods, levels, classes or benchmarks can be prescribed in the requirements for environmental, social and economic performance in the client’s brief, construction regulations, national standards, national codes of practice, construction works assessment and certification schemes, etc. The rules for assessment of environmental, social and economic aspects of organizations, such as management systems, are not included within this framework. However, the consequences of decisions or actions that influence the environmental, social and economic performance of the object of assessment are taken into account.
