Chemical & Mineralogical Properties of Fly Ash
(Malaysian Nuclear Society, 2007)Fly ash is the finely divided mineral residue resulting from the combustion of coal in electric generating plants. Fly ash consists of inorganic, incombustible matter present in the coal that has been fused during combustion ... -
Design, processing and characterization of fly ash-based geopolymers for lightweight concrete application
(Institute for Scientific Information (ISI), 2013-04)The mix design of geopolymers plays important role in obtaining desirable compressive strength. Optimum mix design of geopolymers can be applied for application, such as lightweight concrete. In order to determine the ... -
The effects of fly ash and polystyrene bead additions on compressive strength of foamed cement composites
(Trans Tech Publications, 2013)The effects of both additions of fly ash and polystyrene (PS) beads were studied on compressive strength of foamed cement composites. The increasing amount of fly ash addition up to 6 wt. % has been found to increase the ... -
Fly ash-based geopolymer lightweight concrete using foaming agent
(MDPI, Basel, Switzerland., 2012-06)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 ... -
The influence of curing periods on the compressive strength of fly ash-based geopolymer at different aging times
(Trans Tech Publications, 2012)The results of the current experimental investigation indicate the significant effect of the heating periods on the compressive strength of fly ash-based geopolymers prepared at different alkaline liquid content at both ... -
Lightweight fly ash-based geopolymer concrete
(Trans Tech Publications, 2013)The experiments of this study were preformed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) using normal sand as a fine aggregate and expanded clay as lightweight aggregate. The LWAGC ... -
Mechanical performances of fly ash geopolymer bricks
(American Scientific Publishers, 2013-01)Geopolymer is a new class of three-dimensionally networked amorphous to semi-crystalline alumino-silicate materials, and first developed by Professor Davidovits in 1978. Geopolymers can be synthesized by mixing alumino-silicate ... -
The processing, characterization, and properties of fly ash based geopolymer concrete
(Advanced Study Center Co. Ltd, 2012)In recent years, attempts to increase the utilization of fly ash as a replacement for ordinary Portland cement (OPC) in concrete have increased in significance. Geopolymer concrete does not need the presence of Portland ... -
Properties of lightweight concrete composites with mixture of fly ash and concrete sludge aggregate
(Trans Tech Publications, 2014)Lightweight foamed concrete is a concrete made by cement slurry mixed with foam so that foamed concrete that is much lighter than conventional concrete can be produced. The objectives of this study is to develop optimal ... -
A study on the synthesis of fly ash-based lightweight aggregate geopolymer concrete
(American Scientific Publishers All rights reserved., 2013-01)The experiments conducting for current investigation aimed to study the synthesis process for lightweight aggregate geopolymer concrete (LWAGC) and explore the significance and limitations of the activator content on the ...
