The effect of corrosive environment on geopolymer concrete tensile strength
(EDP Sciences, 2017-02)
This study has the purpose to explore the potential of geopolymer concrete tensile strength in particular on the effects of corrosive environments. Geopolymer concrete, concrete technology used no OPC that has advantages, ...
Characterisation at the bonding zone between fly ash based geopolymer repair materials (GRM) and ordinary portland cement concrete (OPCC)
(MDPI AG, 2020-12)
In recent years, research and development of geopolymers has gained significant interest in the fields of repairs and restoration. This paper investigates the application of a geopolymer as a repair material by implementation ...
Evaluation of the effect of silica fume on amorphous fly ash geopolymers exposed to elevated temperature
(MDPI AG, 2021-01)
The properties of amorphous geopolymer with silica fume addition after heat treatment was rarely reported in the geopolymer field. Geopolymer was prepared by mixing fly ash and alkali activator. The silica fume was added ...
Lightweight Heat Resistant Geopolymer-based Materials Synthesized from Red Mud and Rice Husk Ash Using Sodium Silicate Solution as Alkaline Activator
(EDP Sciences, 2017)
Geopolymer is an inorganic polymer composite with potentials to replace Ordinary Portland Cement (OPC)-based materials in the future because of its lower energy consumption, minimal CO2 emissions and lower production cost ...
Characterization of LUSI mud volcano as geopolymer raw material: A review
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
This paper summarizes the current knowledge about the potential of LUSI mud volcano, East Java, Indonesia as a raw material in geopolymer. Previous experimental study shows that the LUSI mud has a good performance when 5% ...
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 ...
Reviews on the properties of aggregates made with or without geopolymerisation method
(Scientific.Net/Trans Tech Publications, 2012-12)
Aggregates are popular for use in concrete and lightweight concrete applications. Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight ...
Effect of Glass Reinforced Epoxy (GRE) pipe filled with Geopolymer Materials for Piping Application: Compression Properties
(EDP Sciences, 2016)
The aim of this paper is to achieve the highest compressive strength of glass reinforced epoxy pipe with the geopolymer filler content of weight percentage that were used in glass reinforced epoxy pipe. The samples were ...
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 ...
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 ...
