“…This explains the decrease in compressive strength at 28 th day. (Chotard et al, 2005) In fig (4) due to the replacement of HAC by OPC, the setting time is accelerated as compared to that of control. In any cement binary the sulfates and aluminates composition plays an important role in formation of ettringite (Sivakumar et al, 2008).…”

Pastes containing High Alumina Cement (HAC) and Ordinary Portland Cement (OPC) were prepared using Ground Water (GW) and 5, 10, 15 and 20%SF. The setting time and compressive strength of these admixtured cement pastes were measured. The hydrated HAC blends were subjected to DTA/TG and DSC analysis. The recorded spectra were compared with the observed mechanical measurements of these blends. The hydration kinetics is well explained through these results. It is evidenced that 10%SF addition is optimum for this blend.

“…They were obtained by a negative pressure sieve analyzer (FSY-150D, Shaoxing Xinxingsheng Apparatus Co., Ltd., China), a specific surface area analyzer (SZB-9, Hebei Kexi Instrument Co., Ltd., China) with blain method and a laser particle analyzer (LS608, Zhuhai OMEC Instrument Co., Ltd., China). It is indicated that the compositions and finenesses of the two BCAC samples are closed except the content of SO 3 .…”

“…Calcium aluminate cement (CAC) has been widely used in the industries for several distinct advantages over Portland cement, including higher refractoriness, rapid strength gain upon setting, enhanced resistance to abrasion, sulfate attack and alkali-silica reaction [1][2][3]. Setting and hardening of CAC is primarily due to the hydration of monocalcium aluminate (CA, cement notation: 3 ]), but other compounds also participate in the hardening process, especially in long term strength development [4,5].…”

“…Portland cement with high SO 3 and fineness had a potential to produce AFt when the mortar was heat cured in long term [15]. When Portland cement mortars were exposed to SO 2 , under dry condition, more soluble salts (SO 3 wet conditions, less soluble salts (syngenite and gypsum) were noted on analysis [16].…”
