This British Standard, a part of the BS 812 series, describes two methods for determining the sulphate content of aggregates. The first method determines the water-soluble sulphate content of aggregates, which applies to natural and synthetic aggregates to be used as drainage materials or for fill or hard core, e.g. unbound road bases or sub ...

Fine recycled aggregates (FRA) (0/4 mm) are up to now not valorized on a high enough level because of characteristics like an elevated water absorption, higher fines content, and the presence of contaminations. Leftover gypsum residues from the construction site can cause internal sulfate attack when FRA are incorporated into new structures. Concern about this
Abstract Fine recycled aggregates (FRA) (0/4 mm) are up to now not valorized on a high enough level because of characteristics like an elevated water absorption, higher nes content, and the presence of contaminations. Leftover gypsum residues from the construction site can cause internal sulfate attack when FRA are incorporated into new ...
The water-soluble chloride ion content of aggregates for concrete shall be determined in accordance with EN 1744-11998, clause 7, and shall, on request, be declared by the producer. If the water-soluble chloride ion content of the combined aggregate is known to be 0.01 % or lower (e.g., for extracted from most inland quarries), this value can ...
Oct 19, 2018 Celtest are UKAS accredited to perform the acid soluble sulphate test in accordance with clause 12 of BS EN 1744-1. The test involves extracting sulphates from a test portion of the aggregate by dilute hydrochloric acid. The sulphate ion content is determined by gravimetry and expressed as a percentage by mass of the aggregate.

based upon acid-soluble chloride content are higher than those established for water-soluble chloride content. Either of these tests may find chlorides that are present in some limestone aggregates in Midwestern North America. Based upon service records, we know that the chlorides inside these aggregates dont contribute to corrosion.

4.1 Water-extractable chloride, when present in sufficient amount, has a potential to initiate or accelerate corrosion of metals, such as steel, embedded in or contacting a cementitious system, such as mortar, grout, or concrete. This test method is applicable when aggregates contain a high background of naturally occurring chloride (see ACI 222.196 ).

Marine limestone coarse and fine aggregate can be used together only if their combined water soluble chloride content, when tested in accordance with ASTM C1524, is less than 200 ppm. For non-reinforced concrete applications, use marine limestone coarse aggregate that has a weighted loss not exceeding 25% when subjected to five alternations of the sodium sulfate soundness

Feb 22, 2021 To keep the risk on sulfate attack at a reasonable level, the current water soluble sulfate limit in coarse recycled aggregates is established at 0.2% by EN 206 , with no mention of FRA. At these quantities, sulfates are considered the limiting reagent in the ettringite formation reaction so any augmentation would hypothetically lead to more swelling.
Feb 01, 1996 Q. Were designing a concrete structure in Egypt, and I received test results for the aggregate to be used in the concrete. The report lists chloride and sulfate content, but I dont know how to evaluate these numbers because ASTM C 33, Standard Specification for Concrete Aggregates, doesnt give limits for them.

Oct 15, 2014 The sulphate content in RA is a relevant property for this type of material, and it can be measured with tests providing the acid-soluble and water-soluble sulphate contents. Thus, the sulphate contents calculated according to both procedures were correlated, and the data revealed an R 2 factor of 0.96, which means that the relationship between ...
