The current use of sprayed concrete
Due to its flexibility, rapid application and cost effectiveness, sprayed concrete is widely used in building constructions, public works, building pits, tunneling.
Typical properties and parameters of sprayed concrete
The mixture composition should be properly designed to guarantee that the in-situ hardened sprayed concrete will develop acceptable mechanical and physical properties.
Parameters of Sprayed Concrete - Water Cement Ration
The water/cement ratio is a key factor for the workability, performance and durability of concrete.
Fresh concrete properties in Mining industry - South Africa
Sprayed concrete mixtures are of different types, including plain (unreinforced), silica fume, blast furnace slag, fiber-reinforced, high-strength and high-performance, with different hardening properties.
Hardened concrete properties in Mining Industry
In modern tunneling, where immediate ground support is often required, the early-age strength of sprayed concrete is decisive and frequently more important than its ultimate strength.
Aggregates as sprayed concrete constituent material in Mining Industry
Aggregates for sprayed concrete shall comply with the requirements of the national standards and regulations valid in the place of use. They shall be appropriate for placement of sprayed concrete according to the specifications of the work.
