So that it may be certain that a concrete specimen’s mechanical properties reach the strength and deflection imperatives for its intended use, concrete specimens with specific dimensions are prepared, ...

provides a detailed overview of the rheological behaviour of concrete, including measurement techniques, casting and the impact of mix design the estimating, modelling, controlling and monitoring of ...

When choosing a method for monitoring the compressive strength of concrete, it’s important for project managers to consider the impact each technique will have on their schedule. While some testing ...

Consider the following scenarios for a project on which the specified compressive strength (fc’) is 3,500 psi at 28 days. These are all examples of incorrect interpretations of the acceptance criteria ...

Part I in the October 2002 issue began to unravel the mystery of deciphering airflow numbers that are derived from flow bench testing. We addressed the question, "Why test for airflow?" and detailed ...

A probe into New York’s concrete testing industry has prompted city officials to launch a new program to increase the oversight and evaluation of concrete testing at construction projects throughout ...
