The aim of the research is evaluate the segregation possibility of concrete mixture with poor quality aggregates for flowing fluidity. Recently, degrading quality of aggregate is rising as a issue for ready-mixed concrete industry. Poor quality of aggregate causes decreased workability with increasing possibility of segregation directly and indirectly. Therefore, in this research, the segregation conditions of concrete mixtures were observed when the mixtures were designed for flowing fluidity. As a result, under the conditions of using poor quality aggregate, segregation was occurred for flowing fluidity, and for these mixtures, rheological analysis was conducted |
