Mechanical and microstructural evaluations of lightweight aggregate geopolymer concrete before and after exposed to elevated temperatures
(MDPI, Basel, Switzerland, 2013)
This paper presents the mechanical and microstructural characteristics of a lightweight aggregate geopolymer concrete (LWAGC) synthesized by the alkali-activation of a fly ash source (FA) before and after being exposed to ...
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 ...
Fire resistance evaluation of lightweight geopolymer concrete system exposed to elevated temperatures of 100-800 °C
(Trans Tech Publications, 2014)
This paper reports the fire resistance property of a lightweight aggregate geopolymer concrete (LWAGC) material synthesized by the alkali-activation of locally source fly ash (FA) after exposed to elevated temperatures ...
Alteration in the microstructure of fly ash geopolymer upon exposure to elevated temperatures
(Trans Tech Publications, 2013)
This paper represents the mechanical and microstructure changes in geopolymeric material synthesized by the alkali activation of locally source fly ash at high temperatures of 400, 600 and 800 °C. The high compressive ...
Microstructure study on optimization of high strength fly ash based geopolymer
(Trans Tech Publications, 2012)
The compressive strength and microstructural characteristics of fly ash based geopolymer with alkaline activator solution were investigated. The sodium hydroxide and sodium silicate were mixed together to form an alkaline ...
Microstructure study on volcano ash geopolymer aggregate at different sintering temperature
(Trans Tech Publications, 2014)
Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight aggregates. The usage of this material can improve the quality of the aggregates ...
Influence of dolomite on the mechanical properties of boiler ash geopolymer paste
(Trans Tech Publications, 2014)
The waste material from palm oil industry has been increasing since Malaysia was the world largest exported of palm oil mill. The waste such as palm fibers, nut shells, palm kernel and empty fruit bunches are the solid ...
Comparison of geopolymer fly ash and ordinary Portland cement to the strength of concrete
(American Scientific Publishers, 2013-12)
The aim of this study is to evaluate the effect of various fly ash: aggregate ratios by using fly ash (FA) based geopolymer compared to ordinary Portland cement (OPC) on the compressive strength of concrete. The different ...
Comparison of original and sintered LUSI mud from East Java, Indonesia as raw material for making a geopolymer
(American Scientific Publishers, 2013-01)
This paper presents the characterization of LUSI mud from East Java, Indonesia, as a potential raw material for making a geopolymer. Two types of LUSI mud were analyzed, i.e., original LUSI mud and LUSI mud that had been ...
Characterization of LUSI mud volcano as geopolymer raw material
(Trans Tech Publications, 2012)
The mud of mud volcano samples were collected from an eruption site named 'LUSI' (Lumpur "mud" -Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud are SiO 2 and Al 2O ...
