Paper Number: OTC-32419-MS
... 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...

... nanoparticles were blended in 15.9 ppg class G Portland cement slurries in amounts of 0.25% and 0.50% by weight of cement (BWOC). The slurries were cured in atmospheric conditions up to seven days and characterized to determine the influence of the nanoparticles on early age compressive strength development...
