INFLUENCE OF CURING TEMPERATURE ON THE HYDRATION OF THE CEMENT USING GROUND GRANULATED BLAST FURNACE SLAG WITH DIFFERENT BASICITY
نویسندگان
چکیده
塩基度が1.63から1.90の3種の高炉スラグ微粉末（GGBS）を用いて、10、20、および30℃における高炉セメントの強度発現性を評価するとともに、水和生成物の定量、C-S-Hの化学組成分析、空隙径分布の定量などの水和解析を実施した。塩基度が低いGGBSを用いたセメントは、温度が高く材齢が長期になるほど塩基度の高いGGBSとの強度の差は小さくなり、環境温度が強度発現性に及ぼす影響が大きかった。塩基度の低いGGBSを用いたセメントペーストは、水和物全体に占めるC-S-Hの割合が多く、C-S-Hの生成が強度増進に大きく寄与したことが推察された。

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 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 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 کاملRemoval of Hexavalent Chromium in Portland Cement Using Ground Granulated Blast-Furnace Slag Powder
Using ground granulated blast-furnace slag (GGBS) under different alkaline conditions, we studied the mechanisms and extents of Cr(VI) reduction and sorption and compared them to reactions with Portland cement (PC). We also investigated the effects of mixing PC/GGBS ratios on Cr(VI) dissolution after carbonating the substrates. We observed a complete sorption and reduction of Cr(VI) to Cr(III) ...
متن کاملStudying the Hydration of a Retarded Suspension of Ground Granulated Blast-Furnace Slag after Reactivation
This article presents a combined use of a retarder (d-gluconic acid) and an alkaline activator (sodium hydroxide) in a binder system based on ground granulated blast-furnace slag. The properties of the retarder are extending the dormant hydration period and suppressing the generation of strength-giving phases. Different retarder concentrations between 0.25 and 1.00 wt.% regulate the intensity a...
