Abstract In this paper, we report the effect of SiO2 nanoparticle solution on the properties of the neat industry and environmental cements. Moreover, the hybrid SiO2/TiO2 nanoparticles solution impact on the Portland G-class cement. Both destructive and non-destructive tests were used to characterize the properties of the slurries and the cement plugs. Results indicate that the optimum concentration of the nanoparticles improved the elastic, energy absorption, rheological, heat development, and the mechanical load carrying capacity of the cements. The selected optimal nanoparticles concentrations results showed that • the addition of 0.56 % SiO2 by weight of cement (bwoc) increased the uniaxial compressive strength (UCS) of the neat industry cement by 16.7%. • the 0.13% SiO2 bwoc increased the UCS of the neat environmental cement by 50.2%. • the blending of 0.264 %SiO2/0.044% TiO2 bwoc increased the UCS of neat G-class cement by 8.5%. However, by changing the curing temperature and pressure, different results can be achieved.
