Abstract
Corrugated Structures and materials are widely used in the civil engineering field. The use of corrugated rod in concrete slabs and columns is an innovative idea. Corrugated materials arranged by series of ridges and grooves is defined to have higher strength and rigidity. This research focuses on the application of corrugated rods in concrete structures such as slabs and columns by experimental study.
A corrugated wave profile is selected as it is the optimal one and moulds were prepared to bring the corrugation in normal rods. After the corrugation profile is selected and the rods are bent. Samples of size 450 mm x 450 mm x 100 mm for the slabs and 150 mm D x 300 mm H for the cylinders are casted using M25 grade premix concrete with both corrugated rods and normal straight rods and are tested for their flexural and compressive strengths.
The experimental results show that the normally reinforced samples tend to have higher strength than the corrugated reinforced samples. This might be possible due to the pre mature failure of the concrete as observed while experimenting. The stress – strain curve plot of the corrugated reinforced slab samples obtained from the experimental results shows in an abnormal pattern and requires much more detailed study on its application. Further in the process of testing, when the concrete samples were broken in order to check the behavior of reinforcement it was observed the corrugated rods did not have much deformation as against the normal rods that were bent due to loading.
The normal reinforced concrete slabs exhibit bending cracks at mid span and shear cracks at the support as expected, while only bending cracks was found in corrugated reinforced slabs.
