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% ... -
Development of pilot plant for novel geopolymer brick making machine
(American-Eurasian Network for Scientific Information, 2013)With rapid growing country's development and rose in construction activity, rising demand of building materials and increased construction wastes have encouraged the development of new building materials. Geopolymer based ... -
The effect of damp sand content on the geopolymerization reaction of fly ash-based geopolymer mortars
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)The results of the current experimental investigation indicates the significant effect of the natural sand content prepared in damp condition on the compressive strength of fly ash-based geopolymer mortars prepared at ... -
Effect of Solids-To-Liquids, Na2SiO3-To-NaOH and Curing Temperature on the Palm Oil Boiler Ash (Si + Ca) Geopolymerisation System
(MDPI AG, 2015)This paper investigates the effect of the solids-to-liquids (S/L) and Na2SiO3/NaOH ratios on the production of palm oil boiler ash (POBA) based geopolymer. Sodium silicate and sodium hydroxide (NaOH) solution were used as ... -
Effect on strength and hardness of clay ceramic substrate after treatment using koalin based geopolymer glaze
(Trans Tech Publications, 2014)Geopolymerization is an alternative for ceramic industry by using clay based material such as kaolin or calcined kaolin geopolymer. Geopolymer paste is initially produced by alkaline activation of calcined kaolin with NaOH ... -
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 ... -
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 ... -
The influence of curing periods on the compressive strength of fly ash-based geopolymer at different aging times
(Trans Tech Publications, 2012)The results of the current experimental investigation indicate the significant effect of the heating periods on the compressive strength of fly ash-based geopolymers prepared at different alkaline liquid content at both ... -
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 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 ... -
Microstructure studies on the effect of the alkaline activators of fly ash-based geopolymer at elevated heat treatment temperature
(Trans Tech Publications, 2013)Fly ash-based geopolymers are new binding materials produced to replace the ordinary Portland cement (OPC) used in concrete. In this research, the effect of alkaline activators on the compressive strength and the microstructure ... -
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 ... -
Review on fly ash-based geopolymer concrete without portland cement
(Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 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 ... -
Study on solids-to-liquid and alkaline activator ratios on kaolin-based geopolymers
