AASHTO T 232 90th Edition, January 1, 1990 Standard Method of Test for Determination of Lime Content in Lime-Treated Soils by Titration
More info
Description / Abstract:
A method of test is described for determining the percentage of lime in soils or aggregates that have been treated with hydrated lime. It is based on the continuous neutralization of an aqueous solution from the lime-treated specimen for a specified time period. This is accomplished by adding sufficient acid to just neutralize the lime that is continuously being dissolved during the test. The amount of acid used is directly proportional to the lime content of the specimen.
The following applies to all specified limits in this standard: For the purpose of determining conformance with these specifications, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand place of figures used in expressing the limiting value, in accordance with ASTM E29. (This test has a statement pertaining to significant figures.) (No statistical data are available.)
The values stated in SI units are to be regarded as the standard.
Refer to 29 CFR 1910.1200 for regulatory information for chemicals.
This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns associated with its use.
