Effect of sugarcane biomass waste in cement slurries submitted to high temperature and pressure

Cementitious materials are subjected to changes in their microstructure and mechanical behavior when submitted to high service temperatures. In the oil industry, Portland-based slurries are used where conditions imply high temperatures and high pressures, e.g., steam injection or recovery of heavy o...

Effect of sugarcane biomass waste in cement slurries submitted to high temperature and pressure
