Eurocodes
Commentary to Eurocode 2: Like many current national codes in Europe, Eurocode 2 (EC 2) for concrete structures draws heavily on the CEB Model Code. And yet the presentation and terminology, conditioned by the agreed format for Eurocodes, might obscure the similarities to many national codes. Also EC 2 in common with other Eurocodes, tends to be general in character and this might present difficulty to some designers at least initially. The problems of coming to terms with a new set of codes by busy practising engineers cannot be underestimated. This is the backdrop to the publication of ‘Commentary and Worked Examples to EC 2’ by Professor Mancini and his colleagues. Commissioned by CEMBUREAU, BIBM, EFCA and ERMCO this publication should prove immensely valuable to designers in discovering the background to many of the code requirements. This publication will assist in building confidence in the new code, which offers tools for the design of economic and innovative concrete structures. The publication brings together many of the documents produced by the Project Team during the development of the code. The document is rich in theoretical explanations and draws on much recent research. Comparisons with the ENV stage of EC2 are also provided in a number of cases. The chapter on EN 1990 (Basis of structural design) is an added bonus and will be appreciated by practioners. Worked examples further illustrate the application of the code and should promote understanding. The commentary will prove an authentic companion to EC 2 and deserves every success.

Energy efficiency
General guidelines for using thermal mass in concrete buildings: In warm climates, the thermal mass in concrete and masonry helps provide a comfortable living environment and reduce overheating problems, whilst in cooler climates it can be used to absorb solar gains and reduce the need for heating energy. As the basic design requirements for both seasons are not incompatible, housing in more temperate climates can be designed to take advantage of thermal mass on a year–round basis. Examples of such regions include much of northern Europe and the UK. National adaptations: Italian
Fire safety
Comprehensive fire protection and safety with concrete: This document was produced by CEMBUREAU, BIBM and ERMCO. Aimed at specifiers, regulators, building owners, fire authorities, insurance companies and the general public, it shows how concrete can be used to provide comprehensive fire protection including life safety, protection of property and of the environment.

Improving fire safety in tunnels: Road and railway tunnels as well as underpasses can pose risk to the public. Appropriate choice of materials and design elp to minimise the risk. Recent high-profile tunnel fires in Europe have demonstrated the need for appropriate choice of materials for tunnel construction to ensure high safety and reliable availability to traffic. These fires are inevitably of great intensity leading to structural damage and even loss of life. National adaptations: French - German - Italian - Portuguese - Turkish
Guidelines
The European Guidelines for self-compacting concrete: In 2002 EFNARC published their “Specification & Guidelines for Self-Compacting concrete” which, at that time, provided state of the art information for producers and users. Since then, much additional technical information on SCC has been published but European design, product and construction standards do not yet specifically refer to SCC and for site applications this has limited its wider acceptance, especially by specifiers and purchasers. In 1994 five European organisations (BIBM, CEMBUREAU, ERMCO, EFCA and EFNARC), all dedicated to the promotion of advanced materials and systems for the supply and use of concrete, created a “European Project Group” to review current best practice and produce a new document covering all aspects of SCC. This document “The European Guidelines for Self Compacting Concrete” serves to particularly address those issues related to the absence of European specifications, standards and agreed test methods. Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete. Concrete that requires little vibration or compaction has been used in Europe since the early 1970s but self-compacting concrete was not developed until the late 1980’s in Japan. In Europe it was probably first used in civil works for transportation networks in Sweden in the mid1990’s. The EC funded a multi-national, industry lead project “SCC” 1997-2000 and since then SCC has found increasing use in all European countries. Self-compacting concrete offers a rapid rate of concrete placement, with faster construction times and ease of flow around congested reinforcement. The fluidity and segregation resistance of SCC ensures a high level of homogeneity, minimal concrete voids and uniform concrete strength, providing the potential for a superior level of finish and durability to the structure. SCC is often produced with low water-cement ratio providing the potential for high early strength, earlier demoulding and faster use of elements and structures. The elimination of vibrating equipment improves the environment on and near construction and precast sites where concrete is being placed, reducing the exposure of workers to noise and vibration. The improved construction practice and performance, combined with the health and safety benefits, make SCC a very attractive solution for both precast concrete and civil engineering construction.

Consortium independent research on GWP methodologies starts
Brussels, 11 October 2021 – The Global Warming Potential (GWP) is one of the impact categories for Life Cycle Assessment (LCA), a scientific method used to analyse the impacts of goods and services through their entire life cycle. In the construction sector, this method is used to develop Environmental Products Declarations (EPDs), the “building blocks” on which full assessments at building and infrastructure level are performed.

The cement and concrete sector calls for material neutrality in legislation
- There is huge potential in design improvements and in integration of different construction materials in the built environment to achieve energy efficiency and mitigation of CO2 emissions.
- While all actors in the construction market need to cooperate and complement each oth
- er, policymakers have the responsibility to create a level playing field to all building materials.
- Guiding principles to a fair legal framework must include: material neutrality, accurate and correct database, comparisons at the building level over full life cycle of the building.
- The cement and concrete sector is ready to engage with policymakers to ensure a level playing field and reaches out to other material producers to achieve this goal.

Sustainable benefits of concrete structures: Buildings account for around 40% of energy consumption in the European Union. Increased awareness of the role of the built environment in maintaining the sensitive balance between man and nature has placed Sustainability at the heart of modern construction and design. A sustainable approach to construction brings lasting environmental, social and economic benefits to society. Concrete has valuable inherent properties that can significantly contribute to the above-mentioned three pillars of sustainable construction for the benefit of people and society.
