PhD Thesis
Geotechnical grouting is a subject of considerable importance, which has received rather little attention in the way of academic research. The study starts with a comprehensive state-of-the-art review of applicability of different types of ground improvement methods including cement grouting for various geotechnical conditions. This follows in-depth consideration of chemical grouts, which are the only grouts capable of penetrating in fine grained soils and fine rock fissures. The available case histories on dam chemical grouting are analyzed. The experimental work established repeatable design charts for the prediction of chemical grout properties. A reliable correlation between the chemical grout strength and the grouted sand strength is introduced. The thesis specifically addresses the syneresis phenomenon and the strength of chemically impregnated soils. This is a substantially difficult topic and required development of novel approaches and laboratory equipment. The research contributed to further bring grouting practice, which is often contractors' know-how, into engineering discipline. For more information contact info@geoengineeringltd.com
