Properties and durability of concrete containing fluidized

She also observed an improved scaling resistance with 15% CFBC fly ash, but at 30%, the scaling resistance declined. Similarly, Glinicki and Zielinski [19] showed that using 20%, 30%, or 40% CFBC fly ash worsened the de-icing salt scaling of concrete, and the negative effects were proportional with the dosage of CFBC fly ash and its unburned ...

Evaluating Cracking in Concrete: Procedures | Giatec

Aug 17, 2019 · Concrete provides structures with strength, rigidity, and resilience from deformation. These characteristics, however, result in concrete structures lacking the flexibility to move in response to environmental or volume changes. Cracking is usually the first sign of distress in concrete.
