Flakiness index and elongation index are important physical properties of mineral
aggregates which affect the quality of concrete mixes. The presence of flaky and
elongated aggregates beyond certain limits decreases compressive strength and
causes extreme harshness in concrete mixes. The objective of this study is to
improve the workability and strength of concrete with flaky and elongated aggregates
using superplasticizer and mineral admixture and to determine the allowable
percentages of these aggregates in the concrete mixes without adversely affecting
the characteristics of the mix.
