20.500.12556/RUL-72743 Vpliv kemijskih dodatkov in alkalnega okolja na lastnosti apnenih injekcijskih mešanic z dolomitno moko diplomska naloga Influence of chemical additives and alkaline conditions on properties of lime-based injection grouts with dolomite powder V diplomski nalogi smo obravnavali vpliv alkalnega okolja in kemijskih dodatkov, kot sta superplastifikatorja PCE in PPh, na lastnosti injekcijskih mešanic na osnovi apna in dolomitnega polnila. Pripravljeni so bili vzorci (prizmice), ki so bili izpostavljeni različnim pogojem staranja. Sprva smo jih starali 1 mesec pri sobni temperaturi na zraku, nato pa smo jih za 3 mesece izpostavili še pospešenim pogojem staranja v 1M raztopini KOH in povišani temperaturi 60 °C. Preiskave so bile izvedene tako na svežih injekcijskih mešanicah kot tudi na strjenih vzorcih. Na svežih injekcijskih mešanicah smo izvedli standardne meritve pretočnosti, na strjenih mešanicah pa so bile opravljene meritve spremembe mase in volumna ter meritve tlačnih in upogibnih trdnosti. Poleg tega smo izvedli tudi preizkus vpliva glicerol karbonata na karbonatizacijo apnenega veziva. This diploma thesis researches the influence of alkaline conditions and chemical admixtures, such as superplasticizers PCE and PPh, on properties of lime-based injection grouts with dolomite filler. Samples (bars) were prepared and exposed to different ageing conditions. At first, the samples were exposed to room temperature for a 1-month period, after that the bars were exposed for 3 months to accelerated conditions in a solution of 1M NaOH and at the temperature of 60°C. The tests were undertaken on fresh and hardened grouts. On fresh grouts the test of fluidity was carried out, while on hardened bars the changes in weight and volume were measured, and flexural and compressive tests were conducted. Furthermore, the influence of glycerol carbonate on carbonation of the lime binder was also investigated. gradbeništvo diplomska naloga VSŠ apnene injekcijske mešanice kemijski dodatki dolomitna moka preiskave injekcijskih mešanic lime-based injection grouts chemical additives dolomite powder injection grouts investigations true false false [Z.
