Influence of Adding Lime Dust on Compressive Strength and Frost Resistance of Fly Ash Recycled Concrete
The influence of part of fly ash replaced with lime dust on fly ash recycle concrete compressive strength and frost resistance is investigated by compression tests and rapid frost-thawing test. The experimental results show that part of fly ash replaced with lime dust will reduce the early compressive strength of the fly ash recycled concrete; the right amount of lime dust replacing fly ash can raise the latter compressive strength of fly ash recycled concrete, the best replacement proportion is 10%. The anti-frozen capacity of fly ash recycled concrete will reduce by replacing part of fly ash with lime dust, and the amplitude reduction of anti-frozen capacity of fly ash recycled concrete in seawater is greater than the amplitude reduction in sulfate solution and in freshwater.
