EFCA EQ Seal, Scheme outline

EQ SEAL SCHEME OUTLINE OCTOBER 2006

Gives information on the scheme, its requirements and operation

ECP Concrete for energy-efficient buildings – The benefits of thermal mass

ENERGY PERFORMANCE OF CONCRETE BUILDINGS APRIL 2007

Aimed at designers, specifiers, regulators, building owners and the users. This document shows how concrete can be used to both reduce the speed of climate change and to minimise the effects it will have on our built environment.

ECP Fire protection and safety with concrete buildings

FIRE SAFETY BROCHURE APRIL 2007

Aimed at specifiers, regulators, building owners, fire authorities, insurance companies and the general public. This document shows how concrete can be used to provide comprehensive fire protection including life safety, protection of property and of the environment.

CAA information on leaching of admixtures from concrete

AES 9 LEACHING OF ADMIXTURES MARCH 2004

Provides background information on the potential for admixtures to leach from concrete and also the results of research into migration of admixtures from concrete by the UK drinking water inspectorate to their protocol. A protocol that is very similar to that being proposed for adoption by CEN

EFCA presentation to 2005 BIBM conference

MASS FLOW AND RISK ANALYSIS OF TWO SUPERPLASTICIZERS

The paper reports on studies into the fate and risk of two modern polycarboxylate superplasticisers throughout their life-cycle, modelled by applying a mass flow analysis. The emissions are dependent on the particle size distribution, however, the leachable fraction was only found to comprise of monomers or oligomers, not polymers. Due to the low toxicity of the products no significant risks for humans and the environment can be expected. In the case of the polycarboxylate with the labile bonds the leachable fraction is readily biodegradable.

Mass flow and risk analysis of modern superplasticisers

ORGAGEC 05 PAPER, BMG AUGUST 2005

The paper reports on studies into the fate and risk of two modern polycarboxylate superplasticisers throughout their life-cycle, modelled by applying a mass flow analysis. Due to the low toxicity of the products no significant risks for humans and the environment can be expected under realistic conditions.

EFCA presentation to 2004 ERMCO conference

THE IMPACT OF CONCRETE ADMIXTURES ON THE ENVIRONMENT

The presentation looks at the environmental and toxicological effects of admixture use in concrete. The report includes details of admixture leaching from demolition waste.

The paper focuses on the environmental behaviour of superplasticisers such as melamine sulphonate polymers and naphthalene sulphonate polymers. For these types of concrete admixtures mass flow analyses indicated that with correct use and disposal no adverse effects are to be expected for the health of man and environment .

EFNARC / EFCA Guidelines for Viscosity Modifying Admixtures for Concrete

GUIDELINES FOR VMA (document 180)

These “Guidelines for Viscosity Modifying Admixtures for Concrete” represent a practical state-of-the-art document addressed to specifiers, designers, contractors and concrete producers who wish to enhance their expertise and use of VMA’s. The Guidelines covers information for the use of VMA’s in selected applications such as SCC, pumped concrete and underwater concrete and includes sections on problem solving.

CAA Guidelines on Establishing Suitability of VMA

CAA GUIDELINES FOR SCC - VMA

VMA are Viscosity Modifying (segregation resisting) admixtures used in the production of Self-Compacting Concrete. They are not currently covered by European admixture standard EN 934. The UK admixture association (CAA) has produced guidelines for establishing suitability for this type of admixture as required by EN 206-1 and is currently working with the British Standards to convert the guidelines to a full BSI standard. EFCA have provisionally adopted these guidelines.
