Silica Fume Refractory
Silica Fume has a stable pH and a low impurity level and is perfectly adapted to the requirements of refractory castables. Its use improves the flow, mechanical properties (especially hot strength), and durability (via permeability reduction). Silica fume use in refractory castables provides better particle packing. Silica fume use requires…
Silica Fume Oil Well
Silica fume can be used for a primary placement of grout as a hydraulic seal in the well bore, or secondary applications such as remedial operations including leak repairs, splits, closing of depleted zones. The addition of silica fume enables a well to achieve full production potential. The silica fume…
Silica Fume Concrete
Silica Fume Concrete is widely used in concrete and fiber cement industries. In addition to its pozzolanic properties its is also a very good filler due to its particle size. These combined properties lead to an extended life expectancy in corrosive environments (resistance to chlorides, acids and sulphates) and improved…
Silica Fume Shotcrete
Silica Fume Hydraulic is particular due to its high free CaO content, used in a fast setting concrete. Concretes with Silica Fume Hydraulic have higher strength than the average at early age (24 hr and 48 hr). Silica fume use for shotcrete delivers greater economy and time savings, and is…
