Abstract

Shotcrete application has proven advantages over cast-in-place concrete under many different situations. Ease of access, minimal formwork, and higher productivity are prime examples. Its uses have exponentially increased through technical innovations to improve the ready-mix, nozzlemen technique, application surfaces, and to ensure higher dependability of the equipment. Unfortunately, concrete waste is still one of the highest percentages of overall waste in the construction industry. Shotcrete rebound, the material that falls from the wall due to lack of cohesion during installation, has slowly been reduced due to ready-mix alterations over the years, but effective recycling processes have yet to be implemented. Concrete recycling plants have helped to re-route concrete waste from landfills, but they still increase time and money spent cleaning and transporting the material. In some cases, such as gunite solutions, the material cannot be recycled, and becomes waste once it comes in contact with the ground. Instituting reclaim devices underneath shotcrete nozzles will not only catch the rebounded material, but feed it through the main hose for re-application. Since this has never been implemented, initial feedback from industry professionals will set the tone for the marketing and feasibility of this potential product.
