Comparative Study on Ultra High Performance Concrete with and Without Coarse Aggregate by Particle Packing Method

Abstract

This study focuses on the comparative examination of ultra high-performance concrete with and without coarse aggregate using the particle filling method. This research study examines the rheological and mechanical properties of two high-performance concrete construction mixtures, one containing no coarse aggregate and the other containing coarse aggregate below 12.5 mm. The behavior of each mixture in its new state was examined by changing the water cement ratio as 0.26, 0.28 and 0.3. The two minerals used in the mixture are 10% micro silica and 5% metakaolin by weight instead of cement, and sand (M-Sand) and quartz sand produced as quality materials were used. Quartz sand 60 mesh, 100 mesh, 200 mesh etc. Available in colors. In order to prevent cracks in the concrete mixture and increase the ductility of the concrete, 1% steel fiber was used in both mixtures. Some properties of new ultra high-performance concrete (UHPC) were examined using a test rig frequently used to determine the properties of self-compacting concrete. Measure sufficient capacity, excess capacity and capacity of new functional concrete (UHPC). The samples are then cast and tested for compressive strength. It has been observed that the compressive strength of the composite material without coarse aggregate is 5% to 10% higher than that of the composite material with coarse aggregate.
