Abstract

Burned material experiences a decrease in yield strength and elasticity modulus
In this study five compositions of fly ash and perlite-based concrete geopolymer have been burned for 900 degree celcius for 2 hours
The volume of pore decreases for both unburned and burned concrete geopolymer
One of the strength of concrete geopolymer indicator is compressive strength
Both of the results of compressive strength and the pore size are conducted through experimental study
Bet method has been used to measure pore volume of it
UTM machine has been used to calculate compressive strength
It is found that there is a decline trend of pore volume and is the same trend with compressive strength of five compositions of fly ash and perlite-based concrete geopolymer

Keywords: geopolymer compressive strength pore volume passive fire protection
