“…Recently, the use of industrial by-products, such as blast furnace slag (BFS), has increased in the construction industry, due to their potential to reduce CO 2 emissions (Miyasawa et al 2010;Chen et al 2012;Kumar et al 2008). Although BFS blended cement has greater longterm compressive strength and a smaller heat of hydration, it can also have lower compressive strength at early stages of curing and lower carbonation resistance (Gu et al 2014(Gu et al , 2015Cetin et al 2016;Rakhimova et al 2014Rakhimova et al , 2015Matsuka et al 2010).…”

In this study, the development of carbonation resistance in blast furnace slag (BFS) mortar when using silicone oil (SO) is investigated. Moreover, the influence of SO on drying shrinkage and frost resistance are investigated. The results indicate that SO tends to improve the carbonation resistance of BFS blended mortar and reduces drying shrinkage; however, it decreases frost resistance. The water repellency of SO has a positive effect on carbonation and drying shrinkage. Furthermore, there is a possibility that SO prevents the consumption of calcium hydroxide (CH) by carbonation and hydration in portland blast furnace slag cement type B (BB) samples. SO exists in the form of oil droplets in hardened cement pastes and inhibits the relaxation of water pressure at freezing. This is a probable cause for why SO decreases frost resistance.

“…Blast furnace slag (BFS) has been widely used as a mineral admixture in cement and concrete in the concrete industry in order to reduce CO 2 emissions (Miyazawa et al 2010;Chen et al 2012;Kumar et al 2008). In Japan, the replacement levels of BFS are categorized into type A (5-30 wt.%), type B (30-60 wt.%), and type C (60-70 wt.%) according to the Japanese Industrial Standard (JIS).…”

Journal of Advanced AbstractThis paper investigates the compressive strength development of blast furnace slag (BFS) blended mortar mixtures incorporating various mineral admixtures, namely BFS, limestone powder (LSP), and gypsum (CS). BFS replacement ratios of 15, 20, and 25 wt.%; LSP replacement ratios of 2, 3, 4, and 5 wt.%; and a CS replacement ratio of 2 wt.% are employed to improve the strength of BFS blended mortar mixtures. The hydration reaction and products resulting from the use of cement, BFS, and mineral admixtures are quantitatively examined with respect to the XRD/Rietveld method in order to investigate the relationship between the produced hydrates and the strength. Experimental investigation reveals that the mortar mixture with BFS 15 wt.%, LSP 4 wt.%, and CS 2 wt.% exhibits similar compressive strength to an ordinary Portland cement mortar mixture. In addition, the strength is found to be decreased as the BFS replacement ratio increases. At a BFS replacement ratio above 20 wt.%, LSP affects the strength improvement of BFS cement and CS affects the initial strength improvement of BFS cement.
