EXPERIMENTAL COMPARISON OF CONCRETE SPECIMENS HAVING DIFFERENT FORM AND SIZES WITHOUT WALL EFFECT FORMATION

35848

Many studies have been done on geometry’s importance in concrete compressive strength. In this study because of seeing the importance of geometry and slimness in concrete samples, compression strengthes have been analysed by preventing the wall effect process. If the 28 day compression strengthes are examined, the highest strength is obtained from the 100 mm-edged cube sample in 100G with the value 34.2. In the 150 mm-edged cube sample which is a standard sample, the value 33.6 Mpa is obtained and the minimum value is provided that must be 30 Mpa. In the 150x300 mm cylinder sample looking for the minimum value 25 Mpa, 27.6 Mpa strength is obtained while in the 100x200 mm cylinder sample strength of 29.50 Mpa is obtained. In chemical cure performed samples strength increase isn’t very much on the contrary it has been determined that effects on small surfaces of this kind of materials aren’t very much. By the result of the experimental study it has been fixed that it would be useful to choose sample formwork necessary for maximum aggregate size in concrete mixture used in the field. Furthermore pass parameters between samples in different geometry and various models have been suggested.
