A NORDTEST Method for Verification of Self-desiccation in Concrete
(2001) In Cement and Concrete Research 31(2). p.199-203- Abstract
- This article outlines a new NORDTEST method for verification of self-desiccation in concrete. The method involves measurements of the internal relative humidity, RH, on pieces of concrete at one month’s age. The measured RH is then compared with the requirements according to the owner. The new NORDTEST method for self-desiccation permits requirements to be made of the self-desiccation of HPC in accordance with present demands on strength. During the development of the test method experimental studies were carried out on nine concretes with w/c varying between 0.32 and 0.50. Half of the concretes contained five per cent silica fume. The experiments showed a significant effect of cement type, silica fume and w/c on the self-desiccation in... (More)

The experiments showed a significant effect of cement type, silica fume and w/c on the self-desiccation in concrete. The test method was also verified in the field, both when manufacturing the concrete and on site. The method was developed after co-operation between the Technical University of Denmark and Lund University. The experimental studies were performed at Division of Building Materials, Lund Institute of Technology, Lund, 1995-1999. (Less)
