nanosilica - Opis:
- The rapid civilizational progress forces us care more about the natural environment. A huge population produces immeasurable amounts of waste, including vast amounts of waste glass. Therefore, the recycling of waste glass is a challenge that has to be taken on to preserve the balance in our environment. The development of the nanomaterial technology, allowed us to obtain the cement mortars with similar or even enhanced parameters compared to the ordinary ones. These two aspects have become an inspiration for the research, in which waste glass was used along with modern nanomaterial technology. Three groups of mortars, where the natural aggregate was replaced by waste glass (100% – WG, 50% – RWG, 0% – R) were prepared. Each group of mortars was modified with nanosilica admixture of 0%, 1% and 3% (of cement mass). Superplasticizer was incorporated in order to improve the workability of mortars. The workability and density of fresh mortar were determined. The specimens were cured for 7, 28 and 365 days, after which their freeze-thaw resistance and abrasion resistance were evaluated. The study showed that the waste glass aggregate might find application in the construction industry as the mortars produced with the waste glass and nanosilica exhibited improved mechanical properties. The analysis of the results of this experimental research allowed for determining the influence of grain shape of waste glass aggregate on the properties of cement mortar.
