Annotation: The paper deals with the principle trends of development of internal bed soils consolidation at refurbishment with application of compaction and stabilization of foundation bed soils by hardening mortars, field of their application, efficiency of their application. The effect on bed soil composition of the applied technique and stabilizing mortars is determined. The influence of technology in use and fixative solution structures on quality of hardening of soil structure are found out. The recommendations on perfection of the bed soil consolidation methods, building operation techniques, the set of equipment, compositions of hardening mortars and field of their judicious application have been algiven. The proposed anchoring mortars are characterized by small consumption of binding agent by high sedimentation stability, fluidity, great penetrability, resistance to washout during hardening period, lower cost at sufficient strength. It has been established that the field of rational application of the proposed methods of the internal soil consolidation is foundations of refurbished buildings and structures, of fine-grained soils, macroporous undertemped dust and clay soil, including subsiding ones. The recommendations on application of the results of carried out investigation and improvement of complex methods of consolidation of foundation bed soils in execution of construction work of Donbas and at refurbishment of buildings and structures have been worked out.
Keywords: foundations, refurbishment, compaction of foundation bed soil, internal consolidation, perfection of consolidation methods, processing sequence of operations, set of equipment, composition of hardening mortars, research, field of application.
