Silica fume for deserts petroleum cementing

Silica fume for deserts petroleum cementing,this type of silica ash for petroleum cementing is often used as an additive to concrete used for cementing oil wells in the desert. Microsilica powder for oilfield cementing. Usage and precautions:     Generally speaking, the mixing amount of microsilica powder accounts for 5% to 10% of the cement used in the project is the best, and there are two main methods of mixing microsilica powder as follows: (1) internal mixing: in terms of effect, adding an equal amount of water, a silica fume has the effect of improving the performance of the concrete is equivalent to 3 to 5 parts of silica fume can achieve the effect. Adding microsilica powder to cement to replace part of the cement can improve the effect of engineering construction. (2) External mixing: Adding microsilica powder to cement is much better than using cement alone in terms of concrete strength and other properties. But the concrete operation should be paid attention t…
