Abstract

Variety of materials researches is currently underway to develop environmentally friendly concrete is very varied in order to meet the demands of higher cement production. One way is to replace some of the cement with the rest of coal burning PLTU or commonly known as fly ash. Purpose of this study was to determine the effort to improve the physical and chemical properties of fly ash as a partial cement replacement material and influence the reactivity of fly ash has improved by incubating the silica synthesis. The physical examination, fly ash decreased in term of quality and fineness increase in the adsorption of the water content. The chemical test showed that a decline in the percentage of the elements Si and Al but an increase in elemental Fe. It also affects the content of the main compound SiO2 and Mullite are dominated by 77 – 80% fly ash decreased after a treatment process. Reactivity test using XRD found that fly ash has decreased the amount of 3,47% amorphous structure after experiencing the treatment. Fly ash that would be dominated by the reactive silica is a form of amorphous silica, is because the contact surface af amorphous silica is greater than crystalline. This reduction causes no more reactive fly ash after going through the process of treatment and no better used as a partial replacement for cement in concrete.
