EN 520:2004 Gypsum plasterboards - Definitions, requirements and test methods
This document specifies the characteristics and performance of gypsum plasterboards intended to be used in
building construction works including those intended for secondary manufacturing operations. It includes boards
designed to receive either direct surface decoration or gypsum plaster.
This document covers the following product performance characteristics: reaction to fire, water vapour permeability,
flexural strength (breaking load), impact resistance and thermal resistance.
The following performance characteristics are linked to systems assembled with plasterboards: shear strength, fire
resistance, impact resistance direct airborne sound insulation and acoustic absorption to be measured according to
the corresponding European test methods. If required, tests should be done on assembled systems simulating the
end use conditions.
This document covers also additional technical characteristics that are of importance for the use and acceptance of
the product by the Construction Industry and the reference tests for these characteristics.
It provides for the evaluation of conformity of the product to this document.
This document does not cover plasterboards, which have been subject to any secondary manufacturing operations
(e.g. insulating composite panels, plasterboards with thin lamination, etc.).
Dear friends, there is a new annex to this standard - from 2009, if someone of you have it - please share it.

Interim Guidelines for the Use of Self-Consolidating Concrete in Precast/Prestressed Concrete Institute Member Plants
These interim guidelines have been prepared in response to increasing use of and interest in Self- Consolidating Concrete (SCC) in the prestressed concrete industry throughout the United States. (Note: In current North American practice, the terms "Self-Compacting Concrete" and "Self-Consolidating Concrete" relate to the same material.) SCC is a highly workable concrete that can flow through densely reinforced or geometrically complex structural elements under its own weight and adequately fill voids without segregation or excessive bleeding without the need for vibration to consolidate it. The workability of SCC is higher than the highest class of workability associated with normal highperformance concrete typically used in precast/prestressed concrete fabrication plants. This workability can be characterized by the following properties.

Long-life concrete pavements require less frequent repair and rehabilitation and contribute to highway safety and congestion mitigation. The Federal Highway Administration, American Association of State Highway and Transportation Officials, and National Cooperative Highway Research Program sponsored a scanning study to identify design philosophies, materials requirements, construction procedures, and maintenance strategies used in Europe and Canada to build long-life concrete pavements. The scan team observed that concrete pavements in the countries visited are designed for 30 or more years of low-maintenance service life. The countries are responding to pavement-tire noise issues in urban areas by using exposed aggregate surface. Some use catalog designs for pavements and geotextiles as a separator layer between the cement-treated base and concrete pavement. Team recommendations for U.S. implementation include using two-lift construction to build pavements, developing pavement design catalogs, using better-quality materials in pavement subbases, paying greater attention to cement and concrete mixture properties, using a geotextile interlayer to prevent concrete slabs from bonding to the cement-treated base, and using exposed aggregate surfaces to reduce noise.
