Sprayed concrete is a traditional building material, but at the same time it represents a highly innovative technology. The development of sprayed concrete includes material science and advances spraying equipment technology. The performance and characteristics of sprayed concrete depend mainly on the condition of its application, equipments, experience and competence of the crew performing the sprayed concrete operation. This paper presents some aspects regarding a sprayed concrete operation that may have multiple hazards due to the equipment, pressure value and the projection of rebound. In addition, the use of sprayed concrete in underground mining works, involve an adequate ventilation in the application area. Special attention has to be given to chemical admixtures and complementary products use in the constituent materials and finally, in the composition of sprayed concrete.
