- Synopsis
- The broad organization of information related to the transportation time and the quality of ready-mixed concrete at acceptance is considered to not only contribute to the grasp of actual conditions of concrete in general but also to be of use for various studies. This report presents the results of (1) investigations of the transportation time and the time until placing completion. (2) the average values and standard deviations for each product, and (3) the relationship between fresh properties and compressive strength based on the survey on the actual conditions of ready-mixed concrete for building construction.
- Keywords:
- ready-mixed concrete, transportation time, slump, slump flow, air content, compressive strength
