Estimation of Unconfined Compressive Strength (UCS) of Microfine Cement Grouted

BiaoYUAN Micro Fine Cement is mainly composed of CaO, SiO2,Al2O3, Fe2O3 and so on. Other ingredients such as ignition loss, SO3, MgO, insoluble substance and so on should meet the requirements of GB175 and BS EN 197.

Introduction:

BiaoYuan 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, BiaoYuan microfine cements cause no pollution to underground soils or water supplies. 

Feature:

-excellent penetration in tight joints, fissures and pore spaces 

-improved water tightness following proper application 

-better working environment 

-improved grouting efficiency and less waste
