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.
