... areas of Class H cements range from 190-300 m 2 /kg, while the surface areas of Class G cements ranged from 270-380 m 2 /kg. Class C cements have a higher surface area than either Class G or H, which in turn causes it to generate higher compressive strengths earlier. He also noted that the key factor...

..., viscosity, and uniaxial compressive strength. The use of sucrose, Zn species, K species, and Al2O3 was inspired from results presented in previous studies. The slurries were tested under a bottomhole circulating temperature 50° and a static temperature and pressure of 70° and 14 MPa respectively...
