Description
Summary:The possibility of the involving nanotubes as modifiers of the structure of the composite solutions to ensure the safety and durability of the rubble foundation is considered. The greater efficiency of injection can be achieved by integration the composite solutions into the foundation body. The various compounds are integrated into the composite's composition, in particular nano-additives in order to modify the structure of the cement stone, increase the strength properties, increase its crack resistance, change the dynamic viscosity. The strength indicators of the produced composition with the involved boehmite were measured according to GOST methods, and ultrasound analysis was performed. The bentonite clay in a composite solution increases its plasticity and viscosity, maintains resistance to the delamination. The oxides in clay are the basis for hydraulic binders and have a chemical affinity with cement. It was found that most of the particles in P2T2A bentonite don't exceed 10 microns. The addition of the boehmite to the composite system can lead to more dense packing of a cement stone. It's achieved by filling the voids formed during the formation of a cement stone. The composite solution modified by the boehmite has increased the strength and continuity of the structure.
