Standard Method of Test for

Determination of Cement Content in Cement- Treated Aggregate

by the Method of Titration

AASHTO Designation: T 211-90 (2004)

SCOPE

1.1.This method of test covers a procedure for determining cement content based upon the continuous neutralization of an aqueous solution from

the cement-treated aggregate specimen for a specified time period.

This is accomplished by adding sufficient acid to just neutralize the mr ion that is continuously being liberated during the hydration of the cement.

The amount of acid used is directly proportional to the cement content of the treated base sample.

1.2.The following applies to all specified limits in this standard: For the purposes 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 E 29,

Using Significant Digits in Test Data to Determine Conformance with Specifications.

1.3.The values stated in SI units are to be regarded as the standard.
