Strength improvement by partial replacement of portland cement binder (OPC) with condensed silica fume (CSF) has been extensively reported 1,, this can be at the expense of increased water demand .Use of alternative ultrafine materials based on byproducts such as ultrafine ground granulated blast furnace slag (UFS) and ultrafine flyash (UFA) has been less widely reported.
A careful study of ultrafine mill drawings can be found, the unique machine design is the analysis of impeller of superfine grinding machine, the impeller by the inclination angle control design, and very convenient, avoid the material in the air stream is large by sorting, direct access to the powder collector, thus ensuring the good ...
Today it is generally recognized that the use of mineral fillers is one of significant reserves to enhance the efficiency of binders in cost as well as to improve the technical properties of cement composites. Mineral filler corresponding to the
This study is an extension of the above work to determine threshold limits for ultrafine additives to meet durability parameters and reports the effect of some unconventional ultrafine additives like ultrafine slag and ultrafine fly ash as additive in high strength concrete, on the durability properties of concrete.
Application of ultrafine fly ash grinded by low quality fly ash in commercial concrete was studied, and the studied content included fineness test, mortar strength, concrete strength, admixtures adaptability, impermeability and dry shrinkage. Results show that ultrafine fly ash grinded by low quality fly ash had a very good activity and admixtures adaptability, can greatly improve the strength ...
Mar 01, 2019· The GGBS in this work was commercially available ultrafine slag of two sizes (V1 and V2), Nitrogen BET Surface area of V2 (3955 m 2 kg −1) was found to be much higher than the V1 (2435 m 2 kg −1). The (CaO + MgO)/SiO 2 ratio by mass (M, coefficient of basicity) was a reliable indicator of reactivity, Calculated M = of the UFS.
Slag powder processing equipment and technological process. Phrase one: raw material crushing Slag blocks will be crushed to 15mm50mm fineness by crusher. Phrase two: grinding Crushed slag material will be sent to the storage hopper by the elevator, and then the .
The purpose of the study is to obtain a cement grout with improved performance. The grout mixes of the present study contain cement, ultrafine slag (UFS), super plasticizer and water. Properties like flowability, bleeding, compressive strength and shrinkage of cement grouts have been studied.
Mechanical grinding of steel slag is investigated and characterized using Xray diffraction and size analyzer. The results indicate that the obtained ultrafine powders contain active mineral phases suitable for ordinary Portland cement (OPC)Ca(OH)2, 2CaO·SiO2, 2CaO·Fe2O3. We have proved and first pointed out that the steel slag induces phase transition during grinding process and the Blaine ...
