Pemanfaatan bahan limbah pembangkit listrik tenaga uap pada campuran beton k-225
Abstract: Fly Ash is a waste
material from coal burning at thermal power plant. Power Plant Sijantang
produces ± 600 tons per day and it is an environmental problem in the area. In
this study, the waste fly ash substituted into concrete K-225 or fc’=19.04 MPa
amounted to 0%, 5%, 10%, 15%, 20%, 25% and 30%. Results optimum compressive
strength at 5% substitution. After that the additive is added Sikamen NN 0.3%,
1.3% and 2.3%.
The addition of 2.3% additive produces compressive strength of 298.59 kg
/ cm2 very much required at 225 kg / cm2. On the addition of additive 0.3% age
28 day compressive strength of 279.19 kg / cm2, the larger the required amount
of 225 kg / cm2. Without the addition of additive, compressive strength of
218.35 kg / cm2, less than the required amount of 225 kg / cm2. So for concrete
K-225, mix with the substitution of 5% and 0.3% addition of additives can be
used as a standardmixture.
