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 ...
Study on properties and morphology of kaolin based geopolymer coating on clay substrates
(Trans Tech Publications, 2013-12)
The application of geopolymer as a coating was not widely explored by other researchers and therefore the study of kaolin based geopolymer coating applied on different types of clay substrate (unsintered and sintered) was ...
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 ...
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 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 ...
Effect of fly ash/alkaline activator ratio and sodium silicate/NaoH ratio on fly ash geopolymer coating strength
(Trans Tech Publications, 2013)
Fly ash geopolymer coating material potential used to protect surface used in exposure conditions. Ratio of fly ash/alkaline activator and Na₂SiO₃/NaOH play important parameter on determining the best flexural strength of ...
Application of clay - based geopolymer in brick production: A review
(Trans Tech Publications Inc., 2013)
This paper reviews and summarizes the current knowledge and application of clay as a geopolymer material in production of geopolymer brick. As we understand, the nature of source materials give a significant impact to the ...
