Zusammenfassung: | Magnesia binders provide strength to the stone, but have one drawback-low resistance and salt resistance. Increasing water and salinity tolerance, mechanical strength of the hardening magnesia binders can be achieved by introducing the system of micro-aggregates. The quality criteria that determine the activity of the micro filler are: high chemical resistance to water, aggressive media, high mechanical strength. Among the effective microfillers composite magnesia binders include diopside, wollastonite. It is shown that the introduction of 60-80 wt%. wollastonite or diopside with a specific surface of 2000-3500 cm2/g provides significant improvement in strength and water resistance that allows you to lengthen the lifespan and maintain the required quality of products based on composite of magnesia binders. |
