Greek fly ash as a cement replacement in the production of ...

The fly ash produced at the power stations of the Ptolemais region in Northern Greece is rich in Ca due to the origin of the lignite burned and as a consequence it is characterized as a class C fly ash according to ASTM C 618. Because of the high Ca content its use in the concrete production and the production of concrete based products is restricted in Greece and only 10% of the produced fly ...

Fly ash - GCCA

Fly ash A by-product of the coal-fired power industry, fly ash has been added to cement since the 1930s and it is now commonly used to reduce the need for clinker. A by-product of the coal-fired power industry, fly ash is the dust-like particles captured from the flue gases of coal-fired furnaces or removed from the fluidised bed of coal and biomass boilers.

Cement Replacement Materials (CRM) in Concrete - Structville

20/01/2021  As can be seen from the research, the replacement of cement with 20 – 30% fly ash gave better 28-days compressive strength than normal concrete. According to a 2010 study published in Poland , the concrete specimens containing 20 % of fly ash, related to cement mass, gained a compressive strength about 25% higher than normal concrete after 180 days of curing.

The Future of Fly Ash in Concrete CarbonCure

01/12/2020  Fly ash, sometimes called flue ash, has been a popular supplementary cementitious material (SCM) since the mid-1900s. Years of research show that fly ash can decrease concrete’s carbon footprint—and its cost—while increasing its strength and workability. For most concrete producers, fly ash is an important ingredient in concrete mix designs.
