Utilization of liquefied soils in the form of backfilling self-compacting grouts
Chlachula, Jakub ; Krejčí, Pavel (referee) ; Drochytka, Rostislav (advisor)
The bachelor thesis focuses on the research of liquefied soils based on backfilling self compacting grouts. These grouts could be used as bedding for utility lines with lower cost and without unnecessary waste. The prerequisite is that the soil will be stabilized by a suitable stabilizing admixture, which should increase the strength of the composite. It will be necessary to liquefy this composite by using water and suitable liquefaction or plasticizers. As part of this thesis, currently known and used stabilizing admixture and plasticizers are also evaluated, same as the geological situation in the Czech Republic.

Development a new technology of liquefaction and soil stabilization
Chlachula, Jakub ; Krejčí, Pavel (referee) ; Drochytka, Rostislav (advisor)
Nowadays, efforts are being made to reduce the environmental impact on the planet even at soils management. Excavated soils are treated as waste and often end up in landfill or depot landfills. It is an effort to exploit these soils. By adding suitable stabilizing additives, features such as yield fluidity, moisture or compressive strength can be adjusted. This composite can be further liquefactioned by using water and suitable liquefiers or plasticizers. Such iquefactioned soils are a suitable self-compacting grouts dressing for excavation for the laying of utility grids, where it is necessary to fill the hole again. The advantage are low economic demands and the absence of excess waste. In the course of this thesis the situation of soil usability in the Czech Republic will be evaluated and possible technologies of soil adjusters will be described. Further, the known types of stabilizing additives and their influence on soil stabilization will be evaluated and verified. Then, different types of liquefying additives will be evaluated and verified. The aim of the thesis is to develop a new technology of liquefaction and soil stabilization.
