Rapid Hardening Urgent Repair Cement 42.5mpa

Product Description Rapid Hardening Cement 42.5     The product obtained by grinding cement clinker obtained by roasting suitable raw material, consisting essentially of anhydrous calcium sulphoaluminate and dicalcium silicate. Suitable gypsum and 0-10% limestone shall be blended with clinker during manufaturer of rapid-hardening sulphoaluminate cement. The rapid-hardening cement product is hydraulicity binding material. It has high early strength. The code no is R-SAC and with four grades. ♬Fineness: ≥350m2/kg Bending Strength Compressive Strength 42.5 1d 3d 7d 1d 3d 7d ≥6.0 MPa ≥6.5 MPa ≥7.0 MPa ≥33.0 MPa ≥42.5MPa ≥45.0 MPa Strong Point GOOD CHOICE! 1) High early strength and high strength properties Its compressive strength can reach 35-50Mpa within 1 day, 50-70Mpa after 3 days, and it also can grows continually with the increasing of curing age. 2) High froze-resistance property If used at the temperature as low as 0-10℃,which early strength is 5-6 times than that of OPC; if used in 0-20℃ with little admixture, its strength in 3-7d can reach 70-80% of designed strength, with very little strength loss after 300 times of froze-thaw circle. 3) High impermeability: Because of its dense structure, the impermeability of the concrete is 2-3 times than that of OPC in same grade. 4) Anti-carbonation property: It has good anti-carbonation property, and low dry-shrinkage. 5) Corrosion-resistance: Rapid-hardening cement has good corrosion-resistance quality, especially much better in seawater corrosion resistance than that of high anti-sulphate Portland cement, with more than 1 corrosion-resistance coefficient.
