Concrete Paving Quality Control Procedures: Cementitious Heat Generation - Coffee Cup Mobile App
The coffee cup test procedure can be used to monitor the uniformity of cementitious materials that are supplied on a paving project.
How does it work?
To effectively monitor the uniformity of the cementitious materials, it is necessary to perform this test at least once each day that portland cement and/or supplementary cementitious materials (SCMs) are delivered to the project. This test should not be used to accept or reject materials that are supplied. However, it should serve as a process control and troubleshooting aid. If the workability of the mixture changes significantly during construction, the coffee cup test results can be reviewed to identify whether a change in the cementitious materials is contributing to the workability issue. Conversely, the coffee cup test results may indicate that the cementitious materials have been consistent, suggesting that the workability issue is caused by another factor.
