A first series with a standard mortar composition, and a second series with a modified composition (by changing the sand cement factor) in order to obtain a certain target value for the workability.
Lower cementation factors for well cemented samples at laboratory conditions than values observed for poorly consolidated samples denoted that the Archie cementation factor was not indicative of the degree of cementation for the samples studied.
"Everything is possible, because power is the one cementing factor," she said.
One interesting finding was that the risk of infection within 1 year was similar for different fixation techniques, suggesting that the long-term risk of infection may have something to do with patient characteristics, the implant brand used, or cement-related factors, as mentioned above; this requires further study.
Finally, a 'water-to-cement ratio factor' was introduced to the available creep model to account for these influences.
The Taguchi analysis indicated that the design factor "cement augmentation technique" was the main influential factor, whereas "screw shape" was the least influential factor affecting the pullout strength.
The Taguchi's L8 array analysis revealed the design factor "cement augmentation technique" was the main influential factor, whereas "screw shape" was the least influential factor affecting the pullout strength.
The significant factors, cement content, RHA content, percentage of 15 nm SiO2 particles, 80 nm SiO2 particles content, curing media and curing time were used to describe an ANN model.
This paper, which is a contribution to the UNEP series on Eco-Efficient Cements, examines the role of material-based solutions to reducing CO2 emissions from cement production considering factors that could influence implementation.
This study was designed to parametrically assess the influence of both treatment factors (cement volume and number of augmentations), and patient factors (bone and disc quality) on the biomechanical effects of vertebroplasty.
This paper mainly studies the impacts of environmental contamination on the mechanical property of cemented soil, the factors such as cement content, curing age and pH value are taken into consideration.
