| Abstract [eng] |
Master's final project is to create a concrete mixture of high strength and durability using only dry materials, to determine the physical and mechanical properties of this mixture and to predict the production technology of this mixture. The work consists of theoretical analysis and experimental part. Scientific literature analysis was performed in theoretical part. Physical and mechanical properties of identical high performance concret in other scientists researches and the mechanical parameters of the components used for this concrete mixture were analyzed. The economic benefits of this concrete and the demand in the world market, alternative compositions of high performance concrete were foreseen in the analysis of the literature. In the experimental part a high performance concrete was made from merely dry ingredients. Water is the only wet component. The finished concrete has been compared with the similar type of dry mixtures available on the market. This dry mixture has been developed using an alternative mixture composition. Tests of mechanical parameters of mixture samples were completed, frost resistance predicted, porosity measured, economic comparison of material and production price was made . Structure: introduction, literature analysis, research methods, experimental part, conclusions. |
