COMPRESSIVE STRENGTH OF CONCRETE CONTAINING FLY ASH, BRINE, AND ADMIXTURES

The effect of using brine on the compressive strength of concrete containing fly ash and admixtures was studied. The term brine, in this investigation, is restricted to the liquid solution obtained from potash mines that contains salts of sodium, potassium, calcium, and magnesium in the following respective percentages: 9.0, 5.0, 5.2, and 5.8. Four series of tests were performed in this study on concrete made from Type I (ordinary portland) and Type V (sulfate-resisting) cement. High-calcium Saskatchewan fly ash was used as a replacement for cement by weight. Air-entraining agents and superplasticizers were also added to the mixes. The invesigation found that the presence of 40 percent brine in the mixing fluid of concrete made from Type I or Type V cement and containing 35 percent fly ash increased the 28-day strength by about 8 percent over similar concrete containing no brine. The fly ash was an essential factor in obtaining increased strength with brine. The addition of superplasticizer was found to increase the 90-day strength of concrete containing brine.
