Data underlying the research of Performance Evaluation of Low-grade Calcined Clay as a Supplementary Cementitious Material for Sustainable Oil-well Cementing

This dataset comprises of experimentally obtained values, material composition tables and graphs for calcined clay blended oil-well cement slurry samples in terms of compressive strength in distilled water and synthetic formation water of salinity about 105g/L curing at 70C temperature and Life cycle assessment (LCA) of total CO2 emissions and environmental impact factors associated with slurries. Slurry preparation and compressive strength was conducted in accordance with API rp 10B -2 and specifications 10A. LCA was conducted using the ISO 14040 framework. Additionally, XRD xy data of class G oil-well cement is also attached.
