Enhance hydration properties of steel slag using

2012-4-1  Grinding aids have been universally applying to cement production but hardly to grinding steel slag. Grinding aids can save mechanical energy during grinding process, and they also influence on the variations of fineness characteristics , . In the grinding process, a variety of grinding aids have been used.

2017-2-15  Slag cement pastes are prepared with a substitution ratio of 45 wt.%. Mixture of cement (C), grinding slag (GS) and water (W) is prepared using a constant proportion throughout the formulations with a ratio W/L of 0.3 where L = C + GS. Cement paste mixtures are poured into right-prism moulds of dimensions 4 × 4 × 16 cm 3.

SEPARATE OR INTERGRINDING? - Loesche

2017-8-12  vent air requirement when grinding slag separately is around 15 per cent less than when grinding clinker or clinker and slag together, because the mill has to be set up for the lowest common denominator (which is clinker when it comes to early strength). Separate grinding typically requires two mills, or if one bigger vertical mill is

2021-6-3  Slag is referred as granulated slag when subject to grinding accord-ing to the standard NF IN 15167-1 [15]. Granulated blast furnace slag (GBFS) has a morphological form of clear-colour sand. GBFS shares the same main chemical compounds (mainly SiO 2,CaO,Al 2O 3, MgO) [2,11, 16–20] as ordinary Portland cement [20–23]. GBFS has a direct utiliza-

Reactivity Alteration of Granulated Blast Furnace Slag

2019-1-12  Augmenting granulated blast furnace slag (GBFS) content in Portland Slag Cement (PSC) beyond the conventional limit of 70% is the stimulus for this study. Such enhancement other than bringing down the carbon footprint of cement conserves natural resources. However, beyond 70% slag incorporation, early strength gain of PSC is meagre because of its low reactivity. This study explores mechanical ...
