چکیده
This work studies the feasibility to employ a combination of volcanic ash (natural waste) with different raw materials in production geopolymers: fly and mining tailing (considered hazardous solid waste), natural pozzolan, metakaolin. study compares properties geopolymers based on ash, metakaolin, relation 1:1 addition NaOH 15M Na2SiO3 as alkali activators. FTIR XRD assays mechanical tests were employed characterize geopolymers. The results showed that those can be used produce Additionally, revealed prime material composition their mineralogical characteristics influence geopolymerization reaction compression strength, reaching values 35 MPa for ash-pozzolan mixture. pozzolan is good source Al2O3 SiO2 highly reactive activators resulting better comparison mixtures or tailing.

Fly Ash-Based Geopolymer Mortar Incorporating Bottom Ash
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 کاملStudy of Fly Ash Geopolymer Based Composites with Polyester Waste Addition
In the present work, fly ash geopolymer based composites including polyester (PES) waste were studied. Specimens of three compositions were prepared: (a) fly ash geopolymer with 5% PES waste; (b) fly ash geopolymer mortar with 5% PES waste; (c) fly ash geopolymer mortar with 6.25% PES waste. Compressive and bending strength measurements, water absorption test and determination of thermal conduc...
متن کاملAcid Resistance of Fly ash based Geopolymer mortars
Geopolymers are a new promising binder manufactured by activation of a solid aluminosilicate source material with a highly alkaline activating solution and aided by heat. Fly ash, considered to be a waste material is rich in silica and alumina and hence can be used as a source material for manufacture of Geopolymers. These binders have been reported to achieve high early strength and better dur...
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...
