Readymade Ultra Fine Slag (RUFS) was obtained from EnGro Corporation limited, Singapore and was used as substitute to cement. Fine and coarse aggregate used was river sand and broken stone. Specific gravities of cement, ultra fine slag, fine aggregate and coarse aggregate were found to be,, and respectively.
The chemical composition of the slag used in these cements is 35% SiO 2, 16% Al 2 O 3, and 43% CaO. The composition of the portland/slag cement, which is a 25/75 blend, is therefore between the bulk composition of portland cement and the slag. Both of the ultrafine cements permeate fine sands when formulated at high watertocement ratios.
It is the workhorse of the micro fine / ultra fine cement industry. Uses for SuperFine cement include dam foundation grouting, pre and post excavation grouting, soil stabilization and water cutoff grouting. SuperFine''s slag based formulation makes it especially suitable for grouting in aggressive soils.
HCH Ultrafine Grinding Mill Grinding Mills, Ultrafine ... HCH ultrafine grinding mill is especially suitable for ultra fine grinding. After a long period of market application practice and user authentication, the device HC1395 model was certified by the China Association of calcium carbonate for energysaving equipment in China''s calcium carbonate ultrafine processing industry.

Keywords: ultra fine slag, durability, chloride penetration, corrosion, rapid chloride migration test Abstract. Improving the durability of concrete to sustain a longer life span and producing a greener concrete are becoming important criteria in obtaining quality concrete. Incorporating Ground Granulated Blastfurnace Slag (GGBS) as a mineral
allows saving Portland cement without reducing significantly the concrete strength. The ability to obtain ultrafine mineral fillers from industrial byproducts with high specific surface area appears with grinding technology development. Two types of ultrafine ground granulated blast furnace slag .
Cementitious Material For these guidelines this includes portland cement, ground granulated blast furnace slag, fly ash and ultra fine fly ash, raw or calcined natural pozzolans, metakaolin, silica fume, and rice hull ash, or a combination of any of these materials.
