Durability Properties and Microstructure of Ground

May 20, 2014 Ground granulated blast-furnace slag (GGBS) is a green construction material used to produce durable concrete. The secondary pozzolanic reactions can result in reduced pore connectivity; therefore, replacing partial amount of Portland cement (PC) with GGBS can significantly reduce the risk of sulfate attack, alkali–silica reactions and chloride penetration. However, it may also reduce the ...

Sep 01, 2016 The results show that increasing GGBS content leads to a reduction in apparent porosity in the geopolymer mortar cured at room temperature. Total porosity after 28 days curing of the 10S mixture was around 30%. As the GGBS content was increased, the porosity was reduced to 23%, 21% and 18.3% for 20S, 30S and 40S mixtures, respectively.
