Monitoring of Early Age Temperature of Concrete by Mockup Test

Temperature control of immature concrete is very important aspect in concrete technology for avoiding internal cracking due to higher temperatures and temperature gradients, for minimizing cracking due to drying shrinkage.

Generally, before starting the concrete work of a project, a concrete test cube is cast and the variation of the temperature and highest temperature are study to take necessary actions to avoid issue rises due to higher temperature and temperature gradients. In addition, adequacy of the type of formwork to be used and whether any modification required for the form work is also can be decided in the test Depending on the scale of the project, size of the cube to be cast is decided by the senor engineers or they follow the project specification.

Normal practice is to case cube sizes around 1m x 1m x 1m or 2m x 2m x 2m. However, the size of the test block is depends solely on the consultants to the project and the type of elements to be cast.

Thermometers are installed in the middle of the test block and near the surface. Sometimes, additional thermometer is installed in between the middle and the surface. Depending on the results received from the test, decisions are taken proceed with the concreting works.
