Abstract:
In a recent paper, the technological aspects of the extension of the strength versus water-cement ratio relationship beyond the ACI 211.1 Standard Practice were established, and numerical extensions of Abrams' formula were suggested for the cases of high-strength concretes, Type I and Type III cement concretes, or concretes containing chemical and mineral admixtures such as fly ash, superplasticizers, or silica fumes. In addition, flexural strength, ages between three days and one year, and more precise consideration of the air content were considered. This paper utilizes those findings from the standpoint of computer application. Such a computer program would allow for the proportioning for strength considering practically all concrete compositions used presently and in the near future by the construction industry. The development of a window-based software package implementing the proposed extensions is in progress.
