Mechanical Properties of Ordinary and High Performance Fly Ash Concrete
Session
Civil Engineering, Infrastructure and Environment
Description
This paper presents mechanical properties of ordinary and high performance concrete that contain different percentage of Kosovo and Japanese fly ash (FA). Ordinary and high performance concrete contains FA as a replacement of cement in different percentage, and all mix design went under examination. For comparison, a control concrete mixture without FA content was also produced. The fresh properties of ordinary and high performance concrete were observed through slump test and the hardened properties including compressive up to 350 respectively 625 days and drying shrinkage. Test results confirm that it is possible to produce ordinary and high performance concrete with 30% of cement replacement and it is expected results to increase values by time. The use of FA in ordinary and high performance of concrete not only improved the workability but also made it possible to produce quality of concrete C25/30 and C 50/60 at 56 respectively 100 days, while in some cases exceeds the expected compressive strength for ordinary and high performance concrete. To develop this research, 24 different mix designs went under the testing procedures and all examination took place in concrete laboratory in Kosovo and Japan.
Keywords:
Ordinary and high performance concrete, admixture, compressive strength, shrinkage, comparing.
