When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...
In the survey questionnaire sent to the state DOTs, the respondents were asked whether they would agree to be interviewed for the purpose of preparing case examples. Twenty-four state DOT respondents ...
When people hear the term “slump,” most think about posture; think of concrete slump as "concrete posture." In technical terms, slump is a measured indication of the workability, or flow, of a mix.
