Stabilizing Potential of Cement and Fly Ash Mixture on ...

This study was an investigation of the potential of stabilizing an expansive clay soil with the combination of cement and fly ash. The expansive clay soil samples were first subjected general classification tests where three classes of samples evolved; 12% cement optimal mix, 9% cement plus 3% fly ash optimal mix and the 0% (unstabilized ...

CONCRETE Optimizing the Use of Fly Ash in Concrete

The potential for using fly ash as a supplementary cementitious material in concrete has been known almost since the start of the last century (Anon 1914), although it wasn't until the mid-1900s that significant utilization of fly ash in concrete began (for example, USBR 1948) follow-ing the pioneering research conducted at the University of California, Berkeley (Davis 1937).The last 50 years ...
