Sulfuric acid attack on ordinary Portland cement and geopolymer material
(Institute for Scientific Information (ISI), 2013-09)
The resistance of ordinary Portland cement binder towards acid had been widely discussed by researchers. The deterioration effect of this binder may cost high repair expense and rehabilitation. Geopolymer material is a new ...
Microstructural analysis of geopolymer and ordinary Portland cement mortar exposed to sulfuric acid
(Revista De Materiale Plastice, 2013-09)
The vulnerability of ordinary Portland cement (OPC) concrete to acidic attack is a worrying subject regarding the future durability of this binder. On the other side of binder's technology, the new technology of cement ...
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 ...
Study on fly ash based geopolymer for coating applications
(Trans Tech Publications, 2013)
Geopolymer is cementitious binders that do not require the presence of ordinary Portland cement (OPC). Fly ash with geopolymer formulations prepared with mixing alumino-silicate with the alkaline activator solution has ...
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 ...
A study on relationship between porosity and compressive strength for geopolymer paste
(Trans Tech Publications, 2013-12)
This paper presents a study on the relationship between porosity and compressive strength for geopolymer paste. In this research, geopolymer paste was made from fly ash class F based geopolymer mixed with alkaline activator; ...
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 ...
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 ...
Reviews on the different sources materials to the geopolymer performance
(AENSI Publisher All rights reserved, 2013-10)
Geopolymer is manufactured from the aluminosilicate source material in example fly ash, silica fume, kaolin, ground granulate blast slag (GGBS), boiler ash and volcano ash reactivated via alkaline solution. But the different ...
