Methylene Blue Value for Fine Aggregate and …
Methylene Blue Value for Fine Aggregate and Mineral Filler. Submitted by Anonymous (not verified) on Mon, 07/25/2016 - 14:57. Research and field experience have shown that fines free of clay and other harmful materials can be non-detrimental, and even beneficial, for concrete properties. A proposed new ASTM International standard will be used to distinguish between harmful and non-harmful ...

ASTM C1777 - 15 Standard Test Method for Rapid ...
For example, a fine aggregate with high methylene blue value measured by the AASHTO method but low percentage passing the 75 μm sieve may have less effect on concrete performance than a fine aggregate with low methylene blue value measured by the AASHTO method but a high percentage passing the 75 μm sieve. In contrast, this test method expresses methylene blue value based on the entire fine ...

Fine aggregates in Australia must comply with AS2758.1.1 In light of this specification, in 2007 Cement Concrete Aggregates Australia (CCAA) made significant efforts to determine the applicability of this standard towards manufactured sands.2-6 It recommends several useful tests including sand equivalent and methylene blue value.
Cement Concrete & Aggregates Australia Research Report
numerous other specifications) and the Clay and Fine Silt test. Measures of quality include the Methylene Blue Value (MBV) and X-ray Diffraction. The project demonstrates that a combination measure that identifies not only the quantity but also the quality of fines appears to offer the best possibilities of control for manufactured sand. For ...
Cement Standards and Concrete Standards
ASTMs cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, stone admixtures, and aggregates. These ingredients are mixed with water to create concrete which is used as a primary construction material in buildings ...
Relationship between methylene blue values of …
In this study, methylene blue values were determined in fine aggregate samples used to produce ready-mixed concrete. Samples were taken from four different aggregate quarries, and relationships between methylene blue values of the concrete samples produced with these aggregates and some of their properties were investigated. Tests were done to determine the quality of microfine material (i.e ...
