Biomaterials for restoration or replacement of diseased tissues may have any origin.The major characteristic for biomaterials is biocompatibility.All biomaterials,used in medicine (dentistry,in particular),interreact with the organism tissues.And the changes occur both in the materials and the organism tissues.It is considered that there are no "inert biomaterials." The number of allergic diseases and complications is constantly growing all over the world,taking an important place in the structure of infectious and noninfectious pathology[1].Pollen,household,epidermal,and food-borne allergens,and haptens are the most frequent sources of sensibilization. 展开更多

In order to understand the effect of powders ground from reactive sandstone replacing cement on reducing or suppressing alkali-silica reaction(ASR), and to identify the mechanism of suppressing ASR by this powders, mortar and paste containing reactive sandstone powders of four replacement levels ranging from 10wt% to 40wt% and four specific surfaces areas ranging from 210 m^2/kg to 860 m^2/kg were studied. The experimental results showed that incorporation of 40wt% reactive sandstone powders could suppress ASR effectively except for mortar containing reactive sandstone powders with specific surface area of 610 m^2/kg, which disagreed with the most results reported that the higher reactive powder specific surface area, the smaller ASR expansion. By means of fl ame photometry, Fourier transform infrared spectroscopy(FT-IR) and thermo gravimetric analysis(TG), the mechanism of reactive sandstone powders on reducing or suppressing ASR was soluble alkalis type of reactive sandstone powders and the competition of liberating and bonding alkali of cement paste containing reactive sandstone powders,when the ability of alkali bonding was greater than the ability of alkali liberation, ASR caused by reactive sandstone was supressed effectively. 展开更多
