Abstract

Experimental
studies are being carried out to obtain puzzolan materials from agricultural
wastes. The aim of this study was to minimize environmental damage of nut
shells, which are discarded as waste material after the harvesting of crops. Puzzolanic activity test
conducted in experimental study showed that nut shell ash provided compressive
strength at 0.59 level. An analysis of compressive strength results revealed
that compressive strength increases in 28-90 and 180 day values of the
specimens containing nut ash additive. Reference
compressive strength results showed that compressive strength increased by
approximately 57% when water/cement ratio increases and that compressive
strength decreased to 50% level with the increase of additive amount in both
groups of concretes with nut shell additives. ASR test results showed that ash additive used in mortar types
used in 5%-10%-15%-20%-25%-30% ratios had an effect and that it reduced ASR in
mortar type containing 20% additive below 0.20 maximum value which is the
standard value. Improvement of
ash preparation conditions will enable the use of nut shell ash as a mineral
additive.
