Anotācija The complexity of structures and their size have continued to increase, and this has resulted in a greater importance of their strength and deformation characteristics in more serious consequences of their behavior. Creep and shrinkage of High Strength Concrete (HSC) are complex problem because of its brittleness and sensitiveness to cracking. This research deals with experimentally studied mechanical properties of polyvinyl alcohol (PVA) Fiber Reinforced High Strength Concrete (FRHSC). Several kind of concrete mixes have been made adding micro silica and nano silica. The compression and tensile strength, the modulus of elasticity, creep in compression, shrinkage, crack propagation were determined. Wider use of this material permit the construction of sustainable next generation structures with thin walls and large spans that cannot be built using the traditional concrete. The carbon dioxide released into the atmosphere during the cement production process and contributes to the global warming and the development of holes in the ozone layer. This experimental study proves that new elaborated mixes can be successfully used in the production of concrete, thus potentially decreasing the use of cement, which would lead to a reduction of carbon dioxide release into the atmosphere.
