MOISTURE CONTENT - WATER ABSORPTION - FROST SUSCEPTIBILITY

The amount of water that an aggregate can absorb tends to be an excellent indicator as to the strength of theaggregate, or should I say weakness.Strong aggregates will have a very low absorption figure, i.e. below 1%.

Above 4% absorption you need to perform further tests on the aggregate to determine its' acceptability, it may befrost susceptible.A test for water / moisture absorption is described in

BS EN 1097-6 : 2000 : Tests for mechanical and physical properties of aggregates : Part 6 : Determination of particledensity and water absorption

An aggregate with a high moisture absorption is not likely to be an acceptable road building material, e.g. soft ooliticlimestones.

Aggregate that has a honeycombed structure and can ''hold'' water rather than absorb it need not have a highmoisture absorption in the actual solid part of the aggregate, e.g. some slags and good quality furnace bottom ash.These materials themselves will not be subject to frost action providing the road pavements in which they are usedare well drained.

BS EN 12620 : 2002 + A1 : 2008 - Aggregates for Concrete

BS EN 12620 specifies the properties of aggregates and filler aggregates obtained by processing natural,manufactured or recycled materials and mixtures of these aggregates for use in concrete. It covers aggregates havingan oven dried particle density greater than 2,00 Mg/m3 (2 000 kg/m3) for all concrete, including concrete in conformitywith BS EN 206-1 and concrete used in roads and other pavements and for use in precast concrete products.BS EN 12620 also covers recycled aggregate with densities between 1,50 Mg/m3 (1 500 kg/m3) and 2,00 Mg/m3 (2 000kg/m3) with appropriate caveats and recycled fine aggregate (4 mm) with appropriate caveats.

BS EN 12620 specifies that a quality control system is in place for use in factory production control and it provides forthe evaluation of conformity of the products to this European Standard.

This standard does not cover filler aggregates to be used as a constituent in cement or as other than inert filleraggregates for concrete.( I acknowledge that this summary is copyright of BSI. )

BS EN 13043 : 2002 : Aggregates for bituminous mixtures and surface treatments for roads, airfields and othertrafficked areas

This standard supersedes BS 63, Parts 1 & 2, which will be withdrawn in June 2004.

This standard specifies the properties of aggregates and filler aggregates obtained by processing natural ormanufactured or recycled materials for use in bituminous mixtures and surface treatments for roads, airfields andother trafficked areas.

This standard does not cover the use of reclaimed bituminous mixtures.

EN 13043 : 2002 is included in a package of new European Standards being prepared that relate to aggregates.

The existing British Standards for aggregates will be retained until the complete package of European Standardsbecomes available.

BS EN 13055-1 : 2002 (E): Lightweight aggregates : Part 1 - Lightweight aggregates for concrete, mortar and grout

treatments and for unbound and bound applications

This standard specifies the properties of lightweight aggregates and fillers derived thereof obtained by processingnatural, manufactured or recycled materials and mixtures of these aggregates for bituminous mixtures and surfacetreatments and for unbound and hydraulically bound applications other than concrete, mortar and grout.This standard covers lightweight aggregates of mineral origin having particle densities not exceeding 2000kg/cubicmetre or loose bulk densities not exceeding 1200kg/cubic metre.

BS EN 13242 : 2002 : Aggregates for unbound and hydraulically bound materials for use in civil engineering work androad construction

This standard specifies the properties of aggregates obtained by processing natural or manufactured or recycledmaterials for hydraulically bound and unbound materials for civil engineering work and road construction.

It is noted that the requirements in this standard are based upon experience with aggregate types with an establishedpattern of use.Care should be taken when considering the use of aggregates with no such pattern of use, e.g., recycled aggregatesand aggregates arising from certain industrial by-products.
