Characteristics of Asbuton Mix Using Geopolymer Fly Ash Coarse Aggregate as a Substitute for Natural Aggregates
نویسندگان
چکیده
The increase in the number of road construction projects has led to an need for pavement materials (aggregate and asphalt). Currently it takes about 1.6 million tonnes/year asphalt, as well aggregate. Seeing these conditions, is necessary anticipate use waste or natural resources that have not been utilized optimally. In this study, fly ash (PLTU waste) was used aggregate Asbuton (Buton Island rock asphalt) a binder asphalt mixture. As effort save energy, stirring system cold. Based on volumetric characteristics artificial coarse aggregate, only meets specifications VMA value, while VIM VFB values met. mechanical properties (stability flow values) cold mixture replacement with 25% met requirements, but did meet Marshall Quotien requirements

Fly Ash-based Geopolymer Lightweight Concrete Using Foaming Agent
In this paper, we report the results of our investigation on the possibility of producing foam concrete by using a geopolymer system. Class C fly ash was mixed with an alkaline activator solution (a mixture of sodium silicate and NaOH), and foam was added to the geopolymeric mixture to produce lightweight concrete. The NaOH solution was prepared by dilute NaOH pellets with distilled water. The ...

This paper presents the results of study on effect of various parameters on mechanical properties of fly ash-based geopolymer mortar with bottom ash as partial or full replacement for sand. Compressive strength of samples with 10% bottom ash (BA) was comparable to those with only sand. Further increase in bottom ash content decreased the compressive strength. However, the reverse tendency occur...

متن کاملProduction geopolymer materials by coal fly ash
Coal ash is the main waste from power plant. It is estimated that the consumption of the coal for power plant will increase to 240 million tons each year and the coal ash wastes will produce more than 2 million tons per year. Although the utilization of coal fly ash can be reached 74.1%, large amount of coal fly ash and bottom ash still cannot be utilized. The purpose of this research is to dev...
متن کاملCharacterization of Fly Ash for the Production of Geopolymer Cements
Current ASTM standards can be used to provide a degree of characterization of geopolymeric materials, yet the researcher must be aware of differences between hydraulic and geopolymer cementitious materials. The current study assessed the applicability of available ASTM standards that analyze the insoluble content and oxide content of cementitious materials (ASTM C114 and C311), compressive stre...
