ADMIXTURES AND SUSTAINABLE CONCRETE

EFCA has presented an interesting document on the contribution and benefits of the admixtures for a sustainable concrete.

Life Cycle Management of buildings and infrastructures worldwide is becoming a decisive controlling factor in the performance-related requirements of such projects. At the same time building materials required to achieve these performances are becoming scarce, while regulatory framework conditions for the manufacture of these materials are increasing. In order to meet the increasing requirements for protection of the environment, the sustainability of cement in particular, as the most significant component of concrete, must constantly be developed further. Considerable effort has already been made, but the industry nonetheless stands at the beginning of these developments: the employment of SCM (Secondary Cementitious Materials) is gaining momentum and will influence the properties of concrete as a building material. While some of these pozzolanic, latently hydraulic or inert additions, in parallel with their contribution to CO2 emission reduction, show a positive effect on durability. These influence workability and curing as well. Simultaneously a shortage of natural aggregates is emerging, making the mechanical processing of aggregates increasingly necessary, so already today SCM and some fractions of crushed aggregates are being used worldwide in presence of high durability requirements. The content of this contribution is an examination of limitations in achievement of unchanged durability requirements as well as practicable processing conditions and how admixtures are involved in the process. Durability and Sustainability – a Contradiction?

EFCA is now based and operative in Brussels

 

The First EFCA General Assembly in Brussels

Starting from June 2018, EFCA is officially an AISBL based in Brussels. The importance to be more present at European level and to cooperate closely with the other European associations, led to the decision to move EFCA in Brussels. EFCA aims to foster innovation and collaboration with the industry associations.

A new office for a new team, a new look for new aims to achieve.
The attention to the depletion of natural resources and the reduction of CO2 emissions have stimulated a “sustainable” approach in the industry general, and especially in the construction sector. Admixtures play a decisive role in this context, transforming the traditional concrete into a sophisticated material and EFCA will strive to improve the environmental impact of the sector’s products.

EFCA will also follow all the changes and improvements in the field of the innovative solutions as support to a 4.0 construction industry.

EFCA and the environmental benefits of the admixtures at the ERMCO2018 Congress

Nihal Kinnersley on “Admixtures – essential ingredients of 21st century”

On 7th and 8th June an EFCA delegate attended the ERMCO 2018 Congress in Oslo.  The event was important for us, and two particularly interesting presentations, both relevant to our industry were made:

Nihal Kinnersley on “Admixtures – essential ingredients of 21st century”; and Juerg Schlumpf on “Admixtures for a sustainable concrete”.

The first paper focused on the rheological properties of Control Flow Concrete, and showed how the more efficient mix design of Control Flow Concrete can decrease the amount of CO2 production by 27% compared to conventional concrete and self-compacting concrete. The second one focused on durability and sustainability thanks to the admixtures?

Both the presentations highlighted the importance of using admixtures for environmental reasons and how the concrete sector has changed with their introduction for this purpose.

The discussion will continue in the EFCA Position Paper on the “SUSTAINABILITY AND ENVIRONMENTAL BENEFITS OF ADMIXTURES”.

KUB host successful pavilion at Beton 2017, Turkey

EFCA member KUB played a key role in the largest concrete congress and exhibition in Turkey, Beton Istanbul 2017 on 13th-15th April organised by THBB the Turkish ready mix industry.

For the first time ever all of the concrete admixture and construction chemicals producers in Turkey came together under one roof hosted by KUB.

The KUB pavilion

Highly praised by both customers and the manufacturers themselves, the impressive pavilion provided 348 sq. m of combined exhibition and conference space and a programme that included in-depth seminars on nine different aspects of concrete, admixtures and construction chemicals.

EFCA Model EPD verified by ECO Platform

29599867944_e541fab549_oThe EFCA 2015 Model EPD have been confirmed as verified in compliance with EN 15804 and ISO 14025 by the ECO Platform in addition to verification by the German programme holder Institut Bauen und Umwelt e.V.

This additional verification of the EFCA EPD by the ECO Platform provides users with greater confidence in the credibility and comparability of the EPD data.

The modified EPD were presented at an ECO Platform event, co-sponsored by EFCA, held in the Bibliothèque Solvay in Brussels in October.

Standardisation at a signing ceremony in Amsterdam.

Launched by the European Commission, this initiative “aims to improve the European standardisation system and to make sure the system is ready for the challenges it faces from: the changing nature of the economy and diversification of business models; the ever-increasing role of information and communication technology; and the growing importance of services in today’s global value chains, where goods and services are increasingly provided in a package. More generally, this means modernising the existing public-private partnership ….. with the aim to speed up and better prioritise standardisation across the board”

EFCA Joins INGRESS

EFCA has became a member of the INdustry GRoup on European Standardisation Strategy (INGRESS).

The main purpose of INGRESS is:

“to inform European policy makers about industry’s interests and priorities for using harmonised standards in the framework of Regulation EU 1025/2012”

…..by promoting the common interests of industry – based in the EU – in those areas of standardisation policy falling under Regulation 1025/2012 and ensuring that the principle driver of European standardisation should be market relevance.

The Concrete Initiative is launched

Concrete is “The backbone of sustainable construction”

Concrete is the most widely-used construction material in the world. It is part of our everyday lives. However, its ubiquitous nature often means it is taken for granted.

The Concrete Initiative aims to increase awareness of its essential role in creating a sustainable construction sector in Europe.
