Description
Ordinary and high performance concrete (OC - C 25/30 and HPC - C 50/60) made with fly ash has enjoyed numerous application all over the World since 1970. In Kosovo fly ash has not begun to use at all as cement substitution in concrete despite large amount that is produced annually and positive economical - environment aspect. This hesitance has raised due to lack of experience in the concrete engineering field and because chemical composition of Kosovo fly ash, which is classified as non-standard high calcium fly ash (KF). In light of this fact, this study intended to develop further. So, this paper report the consistency, workability, shrinkage, high and ordinary compressive strength of concrete containing different percentage of non-class high calcium fly ash as Portland cement substitution (first case – Kosovo fly ash KF). To develop this research, 14 different mix designs were prepared, starting with 10% fly ash content until 50% of cement replacement and in total more than 250 specimens underwent on testing procedures during different period of curing time. All of this work took place in concrete laboratory in Kosovo.
Keywords:
non-standard fly ash, ordinary and high performance concrete, compressive strength, shrinkage.

Shrinkage, strength of high and ordinary concrete incorporating Kosovo

Ordinary and high performance concrete (OC - C 25/30 and HPC - C 50/60) made with fly ash has enjoyed numerous application all over the World since 1970. In Kosovo fly ash has not begun to use at all as cement substitution in concrete despite large amount that is produced annually and positive economical - environment aspect. This hesitance has raised due to lack of experience in the concrete engineering field and because chemical composition of Kosovo fly ash, which is classified as non-standard high calcium fly ash (KF). In light of this fact, this study intended to develop further. So, this paper report the consistency, workability, shrinkage, high and ordinary compressive strength of concrete containing different percentage of non-class high calcium fly ash as Portland cement substitution (first case – Kosovo fly ash KF). To develop this research, 14 different mix designs were prepared, starting with 10% fly ash content until 50% of cement replacement and in total more than 250 specimens underwent on testing procedures during different period of curing time.
