This paper presents an experimental investigation of bond-strengthening hooks as a new method to increase bond strength along flexural reinforcing bars in reinforced concrete (RC) beams. The proposed method attempts to increase confining stiffness around the flexural bars by placing U-shaped hooks and to prevent premature bond splitting failure. Ten specimens with different numbers and sizes of...

In spite of considerable development in construction sector, the need of manual labour cannot be avoided. The India and other developing countries utilises intensive manual labour in building and infrastructures development. The methods used in these activities are either traditional or designed in a limited way. The present paper aimed to propose improvement in methods of performing these acti...

Rubblization is considered one of the sustainable surface preparation techniques before placing a hot mix asphalt (HMA) overlay that involves breaking the concrete pavement into pieces. The design of the structural overlay thickness for rubblized projects is difficult as the resulting structure is neither a true rigid pavement nor a true flexible pavement. The most important aspect of the desig...

Recent developments in computational design and digital fabrication with concrete enable the realization of freeform geometries that optimize material use. 3D Concrete extrusion Printing (3DCP) is presently one most utilized methods concrete. The expected advantages 3DCP result from shaping without formwork placing only where functionally required. Although these were pointed out more than 20 y...
