The objective of this work was to develop silica sol-reinforced monetite cement matrix and study the related reinforcement kinetics. The preparation of monetite cement powder was done using a microwave processing method with active Ca 2+ present on particles surface as effective silica bonding sites. The incorporated silica sol significantly improved the compressive strength of the final matrix. It was noted surface areas of silica particles in solution together with the solution concentration were the main factors influencing reinforcement level. In vitro bioactivity and biodegradation indicated silica sol can be a beneficial additive to bone cement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
