Utilization of Fly Ash in High Performance Floor Screed Based on Cement and its Influence on Physical Mechanical Properties

Popis výsledku v původním jazyce

This paper deals with the evaluation of a partial replacement of cement by Czech fly ash in high strength floor screed in dosage of 10, 20, 30 and 40% and the assessment of the physical-mechanical properties such as compressive strength, water absorption and bulk density. Used fly ashes are from power plants Poc erady, Opatovice and Tus imice. The experimental study showed that the use of Czech fly ash improves the compressive strength. The bulk density decreases and therefore water absorption increases. Reference samples become clearly the lowest compressive strength at age of 28 days (fc28). A significant increase in compressive strength (fc28) was observed in case of mix design with addition of 10% and 20% of fly ash Tus imice (10%ETU, 20%ETU) and 20% and 30% of fly ash Poc erady (20%EPC, 30%EPC). The addition of 20% of fly ash Poc erady (20%EPC) has noticeable influence on short-term compressive strength (measured at the age of 24 hours).
