The Effects of High Alkaline Fly Ash on Strength Behaviour of a Cohesive Soil

Abstract: Contemporarily, there are 16 coal-burning thermal power plants currently operating in Turkey. This number is expected to rise to 46 in the future. Annually, about 15 million tons of fly ash are removed from the existing thermal power plants in Turkey, but a small proportion of it, 2%, is recyclable. Turkey’s plants are fired by lignite, producing Class C fly ash containing a high percentage of lime. Sulfate and alkali levels are also higher in Class C fly ashes. Therefore, fly ash is, commonly, unsuitable as a… Show more

“…The results indicate that the value of c’ increased with the addition of class C fly ash. These results agree with the observations made by other researchers [ 9 , 35 ]. For the soil stabilized with class C fly ash, the increase in c’ is significant with increase in curing times.…”

“…Scanning electron microscopy (SEM) showed the morphology of the sample of 10% plant fly ash to soil prepared in a high-magnification scanning range (200 nm). Figure 11 shows the random and compacted dense distribution of nanoparticles in the form of granular aggregations of different sizes with the appearance of other semi-spherical and rod-like formations nanoparticles, and the growth method of nanoparticles is roughly consistent with [17,18].…”

“…The inclusion of both FAs in B gradually increases the MDD by 8.5% at 70:30 (FA: B) mix. It may be due to a reduction in repulsive electrostatic force between negatively charged bentonite particles upon inclusion of fly ash particles (Binal 2016). On the other hand, OMC decreases rapidly with FA inclusion.…”
