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 ...
Study on refractory materials application using geopolymer processing
(American Scientific Publishers, 2013-01)
Geopolymer is cementitious binders that do not require the presence of ordinary Portland cement (OPC). Class F fly ash with geopolymer formulations prepared with an alkaline activator (mixture of Na2SiO3 and NaOH solutions) ...
The effect of curing temperature on physical and chemical properties of geopolymers
(Elsevier BV, 2011)
Fly ash-based geopolymers required heat to increase the geopolymerization process in order to obtain higher compressive strength. As such, geopolymer samples were prepared using different curing temperatures (room temperature, ...
Characterization of LUSI mud volcano as geopolymer raw material
(Trans Tech Publications, 2012)
The mud of mud volcano samples were collected from an eruption site named 'LUSI' (Lumpur "mud" -Sidoarjo), East Java, Indonesia for characterization. Analysis showed that, the major constituents of mud are SiO 2 and Al 2O ...
Effect of palm slag filler size on the mechanical and wear properties of brake pad composites
(American Scientific Publishers, 2013-01)
Particle size of filler and other material that involved in brake pad composites are expected to be able to strongly influence the wear properties and performance. Palm slag as a filler in brake pad was investigated in ...
Reviews on the Geopolymer materials for coating application
(Scientific.Net, 2012-12)
The application of geopolymer has been expand in many areas where before this it only used for the production of cement and concrete. One of the new applications of geopolymer is for coating. Metakaolin, fly ash and ...
Classifying Sources Influencing Indoor Air Quality (IAQ) Using Artificial Neural Network (ANN)
(MDPI AG, 2015)
Monitoring indoor air quality (IAQ) is deemed important nowadays. A sophisticated IAQ monitoring system which could classify the source influencing the IAQ is definitely going to be very helpful to the users. Therefore, ...
Application of Firefly Algorithm for Parameter Estimation of Damped Compound Pendulum
(EDP Sciences, 2016)
This paper presents an investigation into the parameter estimation of the damped compound pendulum using Firefly algorithm
method. In estimating the damped compound pendulum, the system necessarily needs a good model. ...
A study on Relay Effect via Magnetic Resonant Coupling for Wireless Power Transfer
(EDP Sciences, 2016)
Wireless power transfer (WPT) transmits electrical energy from a power source to an electrical load wirelessly or without any
conductors. The capability of WPT to transmit the energy is limited. Therefore, a relay was ...
Rubber tire dust-rice husk pyramidal microwave absorber
(EMW Publishing, 2011)
Rubber tire dust-rice husk is an innovation in improving the design of pyramidal microwave absorbers to be used in radio frequency (RF) anechoic chambers. An RF anechoic chamber is a shielded room covered with absorbers ...
