Microfine Cement - PreFine 60/80 (Microfine Cement)

Prefine 60/80 is Green microfine cement based on Ground Granulated Blast furnace Slag (Singapore Green label certificate number: 022-003-2451) developed for special applications, such as injection and grouting. Because of its fineness (D95 <16 µm, D50 <5 µm), PreFine 60/80 has excellent penetration into micro cracks and provides efficient tightness combined with good durability. Prefine 60/80 is designed to meet stringent market requirements such as penetrability; flow-ability, bleeding limit and pod life of more than 1 hrs for tropical regions. In 2015, EnGro has produced and supplied about 2000 tons of premium Prefine 60/80 for fissure grouting applications  jobs at various Thomson line MRT stations with highest quality and short lead time of less than 4 days.  EnGro has in-house capability to tailor performance of microfine cements by changing its fineness, setting time and flow properties to suite the job requirements.

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 6µm to a D95 of 16µm. 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.
