JW High Strength and High Activity Superfine Grouting Agent


JW high-strength and high-activity superfine grouting agent is processed and produced on the basis of sulphoaluminate and silicate series cement clinker by using the most advanced production technology in China, so that the specific surface area of its products can reach more than 700m/kg. The activity of cement clinker can be maximized by using high fineness. It not only has large specific surface area, but also has high early strength, especially strong adaptability of admixture. Under the condition that water requirement does not increase, the slurry has the characteristics of good fluidity.
