What is ECC

The European Federation for Construction Chemicals (ECC) was founded in 2005 and in April 2007 it was registered in conformity with the Belgian law as non-profit Association.

Based in Brussels, the European Federation for Construction Chemicals (ECC) represents construction chemical companies (both raw materials producers for construction chemicals and formulators of construction chemicals) and associations in Europe.

ECC acts as the spokesperson for the construction chemical industry before the European Union institutions and other public authorities, and communicates the industry’s views on policy issues regarding product stewardship, standardisation, innovation and sustainability.

What are Construction Chemicals?

Construction chemicals are typically mixtures of substances (in liquid, paste or powder form) which are applied or used on the construction site.
Examples of construction chemical products are:

  • Additives for cement, gypsum and clay
  • Concrete and mortar admixtures and additives
  • Corrosion protection for reinforced steel in concrete
  • Modified, mineral mortar systems (repair mortars, renders, adhesives…)
  • Hydrophobing agents
  • Additives for Tunneling & Mining applications
  • Reactive resins (resins for injection, bonding, anchoring, as well as flooring resins for park decks and industrial applications)
  • Sealing and bonding products in construction
  • Modified bitumen- based emulsions for waterproofing in construction
  • Liquid applied membranes for waterproofing in construction

Which applications?

Construction Chemicals industry aims to deliver advanced solutions which can meet higher and higher customized requirements requested by the Construction stakeholders (architects, engineers, designers, contractors, applicators). Construction Chemicals provide products & systems used in the large majority of Construction applications : large infrastructures, sky-scrapers and towers, sport stadium, industrial buildings and plants, commercial areas, offshore windfarms, refurbishment and consolidation of concrete structures, tunneling industry, waterproofing systems and concrete protection, and several others. In all those applications Construction Chemicals can give decisive answers to the constantly increasing request of quality, consistency, sustainability and attention to human, social and environmental expectations.

What are Admixtures?

Admixtures are specially formulated products that are added in small amounts to concrete, mortar or grout during the mixing process in order to modify the concrete properties in the plastic and / or hardened state. They are usually water based solutions and can be added to the concrete at up to 5% on cement weight, although most types are added at less than 1.5%.

Most admixtures conform to the requirements of European Standard EN 934 which covers admixtures for concrete (Part 2), mortar (Part 3), grout (Part 4) and sprayed concrete (Part 5). All of these types of admixtures are manufactured by companies who are members of the national associations that form EFCA.

Within these Standards admixtures are categorised further into:

  • Water Reducing/Plasticising
  • High range water reducing/superplasticising
  • Water retaining
  • Air Entraining
  • Set Accelerating (+ non- alkaline set-accelerating)
  • Hardening Accelerating
  • Water Resisting
  • Set Retarding
  • Viscosity Modifying (+ consistence controlling)
  • Shrinkage Reducing Admixtures
  • Bond Improving

Use of admixture in concrete and mortar

  • Improves strength and reduces porosity thus increasing the durable life of the concrete
  • Reduces damage from harsh environments: including marine, freeze-thaw and sub-zero situations
  • Improves quality: better finish and reduced service life repair
  • Reduces embodied carbon dioxide and energy by enhancing the effectiveness of the cement component
  • Reduces noise and energy requirements during placing through increased fluidity (e.g. Self-Compacting Concrete SCC)
  • Preserves natural resources: water and primary aggregates
  • Delivers cost-benefits to the producer and the user
