Optimizing the concrete materials by L9 orthogonal array

This manuscript presents the outcome of an experimental investigation conceded out to optimize the
mix proportions of the concrete by the Taguchi method of parameter design. In order to reduce the
number of mix combination in concrete, the Taguchi method is used. In this project the cement sand
and aggregate are partially replaced by cement as fly ash, river sand as M-sand and the compression
values are taken and the value is compared with the conventional concrete special concrete
compression value is compared with the conventional concrete and S/N value is taken from the
compression value and the comparison of the values are done. In order to attain good strength and to
avoid cracks, sisal fiber is added in the concrete with a percentage of (1, 1.5, and 2).
