Course Summary & Description:
This course provides guidance and information on the proportioning, selection, and application of dry-mix and wet-mix shotcrete as a construction material.
Two types of shotcrete are typically used in construction applications. Shotcrete developed by a dry-mix process is one in which most of the mixing water is added at the nozzle. Shotcrete developed by a wet-mix process is one in which all the materials are mixed before entering the delivery hose. Properly applied shotcrete is a structurally sound and durable construction material that exhibits excellent bonding characteristics to existing concrete, rock, steel, and many other materials. Shotcrete is characteristically defined by having high strength, low absorption, good resistance to weathering, and resistance to some forms of chemical attack.
The goal of this course is to provide an introduction to shotcrete applications, materials, equipment, testing, placement, and quality control procedures. Shotcrete is typically used in a variety of construction applications such as: slope and surface protection, swimming pool construction, tunnel lining, special architectural features, and renovation of existing structures. The course concludes with narrowing down the most essential factors of a successful shotcreting project and emphasizes the importance of having a qualified nozzleman.
