PART 2 The author investigates the mortar bar test described in ASTM C showing that it can give misleading results, as some rocks such as metamorphic quartz and some carbonates exhibit slow but progressive expansion.
Expansion likely to occur in repeated wetting and drying conditions can also be underestimated. Aggregates; Filing Info Accession Number: Alkali-reactivity can be detected in concrete, but the assessment of the aatm and state of progress is almost impossible.
Two types of alkali reactivity of aggregates are recognized: The test method is intended as asgm research and screening method rather than as the aztm of a specification requirement. Proceed to Checkout Continue Shopping.
The test method has been successfully used in 1 research and 2 preliminary screening of aggregate sources to indicate the presence of material with a potential for deleterious expansion when used in concrete. Your Alert Profile lists the documents that will be monitored.
