Project summaryGoal of the project. Development of innovative technologies for hydraulic concretes of new generation, with modified structure, high strength of low anisotropy, mudflow and earthquake resistant, on the basis of resources of Southern Caucasus. Like everywhere in the world, hydraulic structures in Georgia are built using concretes which are not stable against mudflows and seismic tremors. This instability results in the wear of the surface of hydro-engineering structures, their destruction by mudflows and crushing by seismic tremors. Hence the prevention of hydraulic concrete instability by the innovative combined micro- and self(nano)-reinforcement of the concrete structure is a topical goal. The following tasks will be fulfilled:
1.Modification of the concrete structure by micro-reinforcement by silicate fibers. This task has two subtasks: selection of fiber (quantity, length); tests of the properties of prepared concretes;
2. Modification of the concrete structure by self-nano-reinforcement by puzzolanas. This task has two subtasks: selection of puzzolana and a method of its activation, quantity; tests of the properties of prepared concretes;
3. Tests of the properties of hydraulic concrete. This task has 6 subtasks: water permeability, wear resistance, frost resistance, strength (bending, compression, tension) tests.
4. Publication of scientific works, participation in three scientific conferences, submission of two patent applications;
5. Presentation of recommendations on the production of stable hydraulic concretes.
The project personnal includes experienced specialists in the cement and concrete know-how area, doctors of science, authors of numerous published works and patents, former military servicemen and participants in top secrete research.
The project results will be have a favorable influence on the progress of national economy and infrastructure, will contribute to population employment and steady development of the state.
Role of foreign collaborators Col.Dr.Eng.Leopold Kruszka, A.M. ASCE, Head of Dynamic Testing Laboratory has expressed his wish to participate in the project as a collaborator. The collaborator has a great deal of experience in the area of innovative technologies of hydraulic concrete and according to Dr. Leopold Kruszka’s letter dated August 3, 2016 .he is ready to cooperate with project participants and exchange information with the aim of innovative strengthening of hydraulic structures through modification of the concrete structure by volumetric-dispersive macro- and micro-reinforcement by silicate and basalt fibers and self(nano)reinforcement by crystal hydrates of acicular-fibrous-platy habit, by zeolite clinoptiloelllite or clay shale meta kaolin.
a) by volumetric-dispersive macro- and micro-reinforcement by silicate and basalt fiber and rods,
b) by volumetric-dispersive self(nano)-reinforcement by crystal hydrates of acicular-fibrous habit, by zeolite clinoptilolit or clay shale meta kaolin is the innovative method of increasing the stability of hydraulic structures.
The following analyses will be performed in the project: chemical, petrographuc, X-ray-diffractometeric. chromatographic, EN196/EN-1:2000. Euro standard methods will be applied. Tests of concrete for porosity, density, water permeability, crack resistance wear resistance, frost resistance, brittleness, compression-bending-tension tests will be carried out using the equipment of CONTROLS, TESTING and MATEST companies.
