| Abstract | Development of chemical admixtures which can maintain the workability of concrete has been the recent direction of research in the field of construction materials. A study was carried out to examine the effect of dust content on workability and workability retention and the effectiveness of increasing dosage of carrier fluidifying agent (CFA) to solve the problem of the rapid loss of workability of concrete containing unexpected high content of dust. The result is reported in the article. |
