Spinor A12 Micro-fine Cement - Euclid Chemical. Ultra Fine Cement. Spinor A12 is a product range of fine to ultra-fine blast furnace slag binders with a maximum grain size distribution from 48 microns to 6 microns. Spinor A12 consists of grains finer than 12 microns and 12 is the coarser grain size.
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.
Apr 22, 2017· The purpose of the study is to obtain a cement grout with improved performance. The grout mixes of the present study contain cement, ultra-fine slag (UFS), super plasticizer and water. Properties like flowability, bleeding, compressive strength and shrinkage of cement grouts have been studied. Rheological parameters were also studied in order to explain the grout workability. The .
The medium particle size of ultrafine cement is 3-4 micrometers, with a maximum particle size of under 10 micrometers. This high efficiency grouting material has excellent permeation characteristics, making it suitable for grouting fine grain soils, and for the filling of small fissures.

HCH Ultra-fine Grinding Mill - Grinding Mills, Ultrafine ... HCH ultra-fine 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 energy-saving equipment in China's calcium carbonate ultra-fine processing industry.
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 3.15, 2.90, 2.64 and 2.68 respectively.
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 Blast-furnace Slag (GGBS) as a mineral

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 water-to-cement ratios.

The effects of ultra-fine slag (UFS) and silica fume (SF) on the compressive strength and durability-related properties of high-strength concrete were compared, and the mechanism of these effects was analysed. Portland cement was replaced with UFS or SF in amounts of 10% and 15% by mass in cement with a water/binder ratio of 0·25.
dioxide so as to be eco-friendly. This paper presents the effect of ultra-fine slag (i.e. 25% of alccofine) as a replacement of cement for different water to binder ratios (i.e. 0.38, 0.4 and 0.45). The effect of alccofine on the concrete strength properties were studied at 7 and 28 days wherein considerable
MICROFINE CEMENT is a blast furnace slag-based ultrafine cement intended for specialty grouting applications. With a maximum particle size of ten microns and a median particle size of three microns, MICROFINE CEMENT is able to penetrate very small openings such as soil pores and microscopic rock fissures, in order to improve strength and reduce permeability.
As a grinding processing equipment, the ultra fine grinding mill integrates crushing, grinding, grading, and powder collection. It is widely used in coal mines, cement, slag, lime powder for power plant desulfurization, non-metallic ore and other pulverizing fields., Dry materials, hard-to-grind and easy-to-grind materials have very strong adaptability.
