چکیده
The main objective of this research was to investigate the influence curing temperature on phase transformation, mechanical properties, and microstructure as-cured sintered kaolin-ground granulated blast furnace slag (GGBS) geopolymer. varied, giving four different conditions; namely: Room temperature, 40, 60, 80 °C. kaolin-GGBS geopolymer prepared, with a mixture NaOH (8 M) sodium silicate. samples were cured for 14 days afterwards using same sintering profile all samples. that underwent process at 60 °C featured highest strength value: 8.90 MPa, densified microstructure, compared other contribution Na2O in geopolymerization as self-fluxing agent production ceramic low temperatures.

Ground Granulated Blast Furnace Slag
1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...
متن کاملSoil Stabilisation Using Ground Granulated Blast Furnace Slag
Stabilisation is a broad sense for the various methods employed and modifying the properties of a soil to improve its engineering performance and used for a variety of engineering works. In today‟s day soil stabilisation is the major problem for civil engineers, either for construction of road and also for increasing the strength or stability of soil and reduces the construction cost. In this t...
متن کاملCeramics from blast furnace slag, kaolin and quartz
Three new ceramic batches with no traditional fluxes and 30, 50 and 70 wt.% blast furnace slag were studied. The processes of phase formation and densification were estimated in non-isothermal conditions by differential thermal analysis and dilatometry, respectively. After that the degrees of sintering, obtained after heat-treatment at different temperatures and times, were evaluated measuring ...
متن کاملProperties of Cement Pastes Doped with Very High Amounts of Ground Granulated Blast-furnace Slag
In the current work, the properties of cement pastes doped with high amounts of ground granulated blast-furnace slag (HVS) were investigated. Portland cement (PC) was substituted with ground granulated blast-furnace slag (donated as slag) at very high amounts of 85%, 90%, 95% and 100%, by weight. PC paste without any content of slag was used as a reference. Some fresh and hardened properties su...
متن کاملProperties of Foamed Mortar Prepared with Granulated Blast-Furnace Slag
Foamed mortar with a density of 1300 kg/m³ was prepared. In the initial laboratory trials, water-to-cement (w/c) ratios ranging from 0.54 to 0.64 were tested to determine the optimal value for foamed mortar corresponding to the highest compressive strength without compromising its fresh state properties. With the obtained optimal w/c ratio of 0.56, two types of foamed mortar were prepared, name...
