ABSTRACT

The applied research to known about influence of the fly ash additive, as substitute for several cement in mixing concrete, to wall elements with steam curing methods. Specially influence about flexure strength of concrete.
Characteristic compression strength of the concrete is 100 kg/cm2, mix design of concrete with done several variation of percentage the fly ash, variation is 0%, 40%, 50%, 60%. Variation of temperature steam curing is 50oC and 70oC. The set up flexure strength at 28 days old until failure reached.
The result of the laboratory testing until failure indicated that flexure strength to concrete without added fly ash is higher and the best of temperature steam curing is 70oC.

Keywords: fly ash, flexure strength, compression strength
