Concrete as the most consuming Construction materials have long been the answer to the growing needs of human society, which researchers are working on day to day to eliminate its weaknesses with new methods and increase their capability. In the last two decades, the need to build high-rise structures with small-scale structural elements, high resistance And long life Investigating researchers to make concrete more durable and more durable Investigate the researchers has been looking to make concrete more resistant and durable. Scientists' research has led to the emergence of a new type of concrete with extraordinary properties and a very high compressive strength, which is known as the Ultra High-Performance Concrete (UHPC). various mixing designs have been used to make this concrete. The reason for this is the lack of a comprehensive code and the appropriate mixing method for this concrete. the purpose of this study was to obtain a mixing design with high compressive strength, with a change in the ratio of consumables and application of different treatments on the samples, and compare the performance of the steel fibers with polyvinyl alcohol and polypropylene fibers Individual and hybrid. In the present thesis, a non-fibrous base mixing plan is considered, and by changing the size of the aggregates, the ratio of the super-lubricant, the ratio of water to cement materials, the amount of cement consumed per cubic meter and the creation of the operation The standard curing on samples has a compressive resistance of 7 and 28 days, respectively, equal to 98 MPa and 116 MPa. considering that the curing has a significant effect on the increase of the compressive strength for the concrete with a Ultra High performance, in this research various curings such as, curing with water C ° 15, curing with water 60 ° C, curing of autoclave and oven and curing of autoclave and water at a temperature of 60 ° C, which has been curing with autoclave and oven maximum compressive strength, equal to 212 MPa for non-fibrous specimens. concrete is Ultra High, crisp and brittle, and researchers use fibers to compensate for the brittle and ductility of UHPC concrete. in the thesis, steel fibers, modified Polypropylene (Kortta) and polyvinyl alcohol fibers were studied individually and hybrid. The maximum fiber used in the designs is based on laboratory results of 2% volume of concrete. the mixing plan containing 2% steel fibers and a mixing plan containing 1.5% Kortta fiber and 0.5% PVA (hybrid) fiber has created the best mechanical performance for concrete, which mixes between these two mixing plans, hybrid ratios The mixing plan has more ductility of steel fibers. Increasing the macro fiber (steel and Kortta) increases the compressive resistance by 6%, and the micro-polyvinyl alcohol fiber reduces compressive resistance by 14%, and increases tension for the first crack in Ultra High concrete performance.
