(HA) in nano-grade.Sodium alginate solution was added in to the cement in order to make it could be injected through a 16-gauge needle.The cement was injected into cylindrical defects(2mm in diameter) in the femoral condyles of New Zealand rabbits.And specimens were harvested in 4 to 16...
Compressive strength is one of the most important properties of concrete in the hardened state. As well as compressive strength, other very important properties worth mentioning are compactness, workability, durability, cement class AFNOR NF EN 197–1 (2012), gravel/sandG/Sratio, granular rangeD/d...
The article discusses on the case of a patient with pyknodysostosis who had osteoarthritis of both hips, which were managed with a total hip arthroplasty with cement. In 1977, the patient had a low-friction arthroplasty with cement performed on the left hip. In 1984, he had chronic osteomyel...
In class M cements, it is possible to include different SCMs. In particular, one could include a reactive and a non (poorly) reactive SCM. An example is the use of limestone filler with metakaolin. Recent studies show that 45% of substitution by 30% of metakaolin and 15% of limestone ...
Overall, it was concluded that, in addition to minimum strength class and maximum w/c ratio (and in some cases cover depth), specifying minimum cement content for concrete durability was not necessary. 展开 关键词: codes of practice and standards concrete technology & manufacture strength & ...
