diplomska naloga
Abstract
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.

Secondary title: |
Influence of chemical additives and alkaline conditions on properties of lime-based injection grouts with dolomite powder |
Secondary abstract: |
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. |
