Microfine Cements are blast furnace slag based cements composed of ultrafine particles and are designed for injection into loose soils, rock and concrete. They feature a maximum grain size ranging from a D95 of 6& 181m to a D95 of 16& 181m. Depending on the application and the permeability of the strata, different grain size can be used. It is suited for stabilizing or sealing all earthen foundations especially for permanent structures such as tunnels, dams, deep foundations and oil storage tanks. Because they cure into a hardened concrete, Microfine Cements cause no pollution to underground soils or water supplies. Benefits:=-Excellent penetration in tight joints, fissures and pore spaces -Improved water tightness following proper application -Better working environment -Improved grouting efficiency and less waste Technical DataPRODUCT Unit DMFC-600 DMFC -800 DMFC -1200 Appearance Grey Powder Grey Powder Grey Powder Odor none none none Toxic none none none Specific Gravity Kg/dm3 ~3 ~3 ~3 Specific Surface Area m2/kg ?600 ?800 ?1200 Grain Size D50 & 181m <6.75 <4.38 <3.21 Grain Size D90 & 181m <16.31 <9.68 <7.55 Grain Size D95 & 181m <22.97 <12.86 <10.51 Setting Times(Measured by Vicat needle) Initial set min 60 120 60-120 Final set min 120 150 120-150 Compressive Strength 3 d Mpa 25 25 25 7 d Mpa 45 45 45 28 d Mpa 60 60 60
