Fly ash is industrial residue from the coal combustion in electric and steam generating plants recognized as an environmental pollutant. contains a high concentration of silica alumina can be used geopolymer concrete. Studies use fly concrete mixture has been developing recent decades. This review focuses on characteristics hybrid concrete, its resistance peat environment. The made by activatin...

Abstract Peat is a soil that has high compressibility property beside having low bearing capacity. Due to these problems, the peat not suitable for construction purposes. Coconut waste an example of agricultural waste. In context environmental sustainability, use coir in geotechnical applications desirable. This research was conducted study stabilization by using Coir Fibre Ash (CFA) partially ...

20 The aim of this paper is to assess the Zn isotopic variabilty in feed materials and in 21 combustion by-products collected from three different coal-fired power plants and to 22 develop a generalized model that accounts for the Zn isotopic fractionation occuring 23 during coal combustion processes. Partitioning of Zn between combustion residues and 24 the isotopic composition of feed materia...

The aim of the study was to determine if an As-contaminated soil, stabilized using zerovalent iron (Fe(0)) and its combination with gypsum waste, coal fly ash, peat, or sewage sludge, could be used as a construction material at the top layer of the landfill cover. A reproduction of 2 m thick protection/vegetation layer of a landfill cover using a column setup was used to determine the ability o...

FABA is a by-product of coal combustion in power plants comprising fly ash (FA) and bottom (BA) ratios 80/20. Fly has great potential as mineral ingredient concrete, while compromises its strength durability. However, both materials are used to improve the durability structures sulfate, chloride, acidic environments. This research evaluated properties blended high-volume such strength, porosity...

The durability of concrete has a profound impact on the service life structural elements. Indonesia extensive peat soils, which provide highly aggressive environment for structures. Geopolymer demonstrated good when exposed to acid /sulphate conditions similar those encountered in soils. This paper investigates performance geopolymer concretes produced using Indonesian type F fly ash under sulp...

High content of organic matter and fibre within peat results in a high degree porosity; causing to have low bearing capacity. This study focuses on the application nylon as reinforcing material with fly ash chemical stabilizer enhance strength peat. The standard proctor tests were conducted obtain optimum moisture (OMC) for all samples which these OMC is then used sample preparation both Unconf...

Our earlier experiments in small composters (220 l) indicated the favourable effect of ash from co-incineration of sorted dry waste on the composting of catering waste. The aim of this new study was to clarify further, at a scale of 10 m3, the feasibility of using similar ash as an additive in composting. Source-separated catering waste was mixed with bulking agent (peat and wood chips) and fue...
