%X <span style=\"font-family:Verdana;\">In this study, the possibility of using corn cobs as an organic aggregate
in producing lightweight concrete ha</span><span style=\"font-family:Verdana;\">s</span><span style=\"font-family:Verdana;\"> been investigated. First, some important physical properties of corn cob
have been determined in the laboratory. These properties are as follows: weight
to volume ratio (unit weight), water absorption rate and granulometric
analysis. Later on, 4 concrete mixtures have been prepared according to </span><span style=\"font-family:Verdana;\">the </span><span style=\"font-family:Verdana;\">workability of concrete
and standar</span><span style=\"font-family:Verdana;\">d</span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\">s
specified in Turkey. After that, unit weight, heat transmissibility coefficient
and 28-day pressure strength of these 4 concrete samples have been determined
using machines measuring these properties. The 28-day pressure endurance value
has been found between 1.4 - 56.25 kgf/cm</span><sup><span style=\"font-family:Verdana;\">2</span></sup><span style=\"font-family:Verdana;\">,</span></span><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:Verdana;\">heat transmissibility coefficient ha</span><span style=\"font-family:Verdana;\">s</span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\"> been found between 0.19 -
0.35 Kcal/m<span style=\"white-space:nowrap;\">&amp;#8729;</span></span><span style=\"font-family:Verdana;\">h<span style=\"white-space:nowrap;\">&amp;#8729;</span><span style=\"white-space:nowrap;\">&amp;#730;</span>C and unit weight of samples have been found between 800 - 1520
kg/m</span><sup><span style=\"font-family:Verdana;\">3</span></sup><span style=\"font-family:Verdana;\">. Lastly</span></span><span style=\"font-family:Verdana;\">,</span><span style=\"font-family:Verdana;\"> these
properties of concrete samples have been compared with other lightweight
materials being used in </span><span style=\"font-family:Verdana;\">the </span><span style=\"font-family:Verdana;\">construction of buildings.</span>
