ABSTRACT
Fly ash is a waste product from coal based thermal power stations. About seven million tons of fly ash is being produced annually from these thermal power stations in Turkey. Concerted efforts are needed to make the material used to a great extent.
These paper give the results of an investigation on the performance of fly ash concrete made with ASTM C class fly ashes from two sources. PC42,5 cement used in the experiments conforms to TS19 (Turkish Standards).
A comparison between concretes with and without fly ash was provided for various aspects. All the concrete mixtures contained polyhydroxy carbon salt plasticizer which complies with ASTM C 494-81 Type D. Their workabilities were kept constant.
As freshly-mixed concrete properties slump, unit weight, air content, setting time and bleeding values were determined.
As mechanical properties compressive strength and were measured after......
