THE INVESTIGATION OF REPLACEMENT EFFECT OF MICROSILICA FOR THE METAKAOLIN-BASED ADDITION IN THE HEAT-RESISTANT CONCRETE
https://doi.org/10.17073/1683-4518-2013-6-43-48
Abstract
The comparative study is presented in the article for the influence of both microsilica and metakaolin-based additions on the hydration of alumina cement and on the cement stone structure forming after the hardening and burning. It was established that metakaolin-based addition being combined with alumina cement provides the cement’s mineral’s passing into solution more intensively than the microsilica addition does, and also that the hydration of the composite with metakaolin-based addition goes quicker than that of the composition with microsilica addition does. The metakaolin-based addition comparing to the microsilica addition improves the mechanical properties of the heat-resistant fire-clay-based concrete, the ultimate strength in compression after the hardening and sintering of the samples with metakaolin additions higher by 5–27 % than that for the samples with microsilica addition. Ill. 10. Ref. 16. Tab. 1.
