Review on fly ash-based geopolymer concrete without portland cement
(Universiti Malaysia Perlis (UniMAP), 2010-10-16)
This paper summarizes the factors that affect the properties of fly ash-based geopolymer concrete. Alkaline activator is an important material that controls the properties of geopolymer concrete. The workability of fresh ...
Fly ash geopolymer bricks- a review
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
Fly Ash geopolymer bricks is one of the alkali activated material. Bricks are the only man-made building materials that testify to their use since the early human civilization. Since fly ash is being accumulated as waste ...
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 ...
FTIR and XRD characterization of kaolin geopolymer based on solids-to-liquid and alkaline activator ratios
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
This paper covers the results of X-ray powder diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) in assessing the phase identification and functional group of kaolin geopolymer based on the different ...
Fly ash porous material using geopolymerization process for high temperature exposure
(MDPI AG (Basel, Switzerland), 2012-04)
This paper presents the results of a study on the effect of temperature on geopolymers manufactured using pozzolanic materials (fly ash). In this paper, we report on our investigation of the performance of porous geopolymers ...
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 ...
Effect of curing regimes on metakaolin geopolymer pastes produced from geopolymer powder
(Scientific.Net/Trans Tech Publications, 2012-12)
The properties of metakaolin geopolymer paste are affected by the alkali concentration, the initial raw materials, solidification process, and amount of mixing water as well as the curing conditions. This study aimed to ...
Potential of marine clay as raw material in geopolymer composite
(Scientific.Net/Trans Tech Publications, 2012-12)
In this research, marine clays has been studied its potential as a matrix composite materials that tend to be used as alternative materials to concrete. The study shows that marine clays which mixed with appropriate ...
Strength and microstructural properties of mechanically-activated kaolin geopolymers
(Trans Tech Publications, 2012-12)
Kaolin geopolymers exhibit low strength properties due to its plate-like nature which contribute to smaller surface area for geopolymerization reactions. Layered kaolin structure only allows very little, if any, substitution ...
