Abstract:
The degree of quality of a shotcreting job is dependent upon just about the same things as any conventional cast-in-place concrete project. The finish must be performed by knowledgeable, well-trained personnel, good curing practices must be adhered to, and adequate quality control procedures must be followed. However, there are many aspects that make it different from most concrete jobs. The finish shotcrete layer is generally built up slightly beyond the alignment devices, and then cut back by the finishers once it has started to stiffen. As with all cementitious compositions, shotcrete must be properly cured. The quality of the project is highly dependent upon the skill of the shotcrete nozzleman.
