This course discusses shotcrete materials. Properly applied shotcrete is a structurally sound and durable construction material which exhibits excellent bonding characteristics to existing concrete, rock, steel, and many other materials. It can have high strength, low absorption, good resistance to weathering, and resistance to some forms of a chemical attack. Many of the physical properties of sound shotcrete are comparable or superior to those of conventional concrete or mortar having the same composition. Improperly applied shotcrete may create conditions much worse than the untreated condition. Shotcrete is used in lieu of conventional concrete, in most instances, for reasons of cost or convenience. Shotcrete is advantageous in situations when the formwork is cost prohibitive or impractical and where forms can be reduced or eliminated, access to the work area is difficult, thin layers or variable thicknesses are required, or normal casting techniques cannot be employed. Additional savings are possible because shotcrete requires only a small, portable plant for manufacture and placement. Shotcreting operations can often be accomplished in areas of limited access to make repairs to structures.

This course discusses the chemical admixtures that may be used in concrete on projects. These are air-entraining admixtures, accelerating admixtures, water-reducing admixtures, retarding admixtures, water-reducing and retarding admixtures, water-reducing and accelerating admixtures, high-range water-reducing admixtures, and high range water-reducing and retarding admixtures. All of the latter are discussed in ASTM C 494. Chemical admixtures to produce flowing concrete are discussed in ASTM C 1017. Other admixtures may be used when their use on the project results in improved quality or economy. When admixtures are considered to provide special concrete properties, trial batches with materials representative of those that will be used for the project should be proportioned and tested. Admixtures proposed for use during construction should be checked with trial batches, using the actual project materials in the Division laboratory.

Transducers have been universally accepted for use in concrete structures. Transducers utilize two different electromechanical principles, namely changes in wire tension cause change in the electrical resistance of the wire, and also changes in the temperature of the wire cause change in its electrical resistance. The strain meter, joint meter, stress meter, pore pressure cell, and the reinforced concrete meter utilizes both principles to measure deformation and temperature changes.
