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; ...
Investigating the possibility of utilization of kaolin and the potential of metakaolin to produce green cement for construction purposes-A review
(INSInet Publication, 2011-09)
Geopolymers are inorganic alkali aluminosilicate gels, formed from reaction of mineral clays or aluminosilicate-bearing industrial wastes, and treated with alkali silicate solution at 40-80°C. Geopolymers have been studied ...
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 ...
Compressive strength and morphology of fly ash based geopolymer as artificial aggregate with different curing temperature
(Trans Tech Publications, 2014)
This paper presented the compressive strength of geopolymer paste with different NaOH concentration and morphology analysis for sintered artificial aggregate. This artificial aggregate was produce based on mix design with ...
Study on solids-to-liquid and alkaline activator ratios on kaolin-based geopolymers
(Elsevier Ltd., 2012-10)
Kaolin and alkali activator were mixed with the solids-to-liquid ratios in range of 0.60-1.20 (Al 2O 3/Na 2O molar ratio of 0.63-1.27). Sodium silicate and sodium hydroxide ranged between 0.16 and 0.36 (SiO 2/Na 2O molar ...
Potential application of kaolin without calcine as greener concrete: A review
(INSInet Publications, 2011-07)
Kaolin is a white raw material that has an essential constituent which makes it ideal for industrial applications such as green concrete. Based on a historical review, it appears that green polymeric composites created by ...
New processing method of kaolin-based geopolymer brick by using geopolymer brick machine
(Trans Tech Publications, 2014-01)
With increased activity in construction, deficiency of building materials and construction waste improvements have encouraged the development of new building materials. Conventional construction bricks are usually made ...
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 ...
Properties and behavior of Geopolymer Concrete Subjected to Explosive Air Blast Loading: a review
(EDP Sciences, 2017)
The severe damage to civilian buildings, public area, jet aircraft impact and defense target under explosive blast loading can cause a huge property loss. Most of researcher discusses the topics on design the concrete ...
The Effect of Different Ratio Bottom Ash and Fly Ash Geopolymer Brick on Mechanical Properties for Non-loading Application
(EDP Sciences, 2017)
This paper studies the finding of strength and water absorption of geopolymer bricks using bottom ash and fly ash as a geopolymer raw material for non-loading application with minimum strength. The study has been conducted ...
