Fast setting concrete powder (Shotcrete Powder)

Fast setting concrete powder (Shotcrete Powder)

Uses

The use of Admix Accelerator seems necessary in areas where concrete needs to set faster than normal, such as concrete repair works, reinforcement of concrete structures, and generally in areas where there is a risk of roof and wall collapse.

Shotcrete structures can be a very effective and economical application for ground control and wall stability and for works such as the restoration and rebuilding of old buildings, the construction of concrete pavements and the stability of stone and earth slopes and the stabilization of underground structures. Shotcrete can also be defined as mortar or concrete that is sprayed onto a surface with compressed air at high speed. The advantages of shotcrete are that it does not require molding compared to other maintenance methods, is suitable for irregular surfaces, and provides the opportunity to transport materials to inaccessible places. Shotcrete is usually made on steel mesh, but for fire reinforcement, the right amount of steel fibers + micropropylene fibers can be used instead, and much better results and performance can be obtained on steel mesh than shotcrete.

Description

Shotcrete Powder is the most important and effective factor that accelerates the instant setting of the concrete and reaches the desired strength in the shortest time in this concrete mixture made by using a special spray pump in the form of spray. In addition to calcium and magnesium, the presence of substances that play a role in PH adjustment in this product causes the cement to set quickly.

Advantages

  • By stabilizing the roof and wall surfaces of the tunnels where there is a risk of falling, it provides the possibility of molding and concrete implementation.
  • Suitable for underground mines for stability of excavations.
  • Stability of permanent excavations such as diagonal roads
  • Stabilization of the surface where there is a risk of falling.
  • Strengthening structures.
  • Implementation of temporary and permanent shell structures.

 

Recommended Dosage

The exact amount of use should be calculated according to the materials and requirements of the project, but still 2 to 5 percent by weight of cement and in special cases up to 7 percent are inconvenient.

Application

The calculated amount is added to the mixture of cement, sand and crushed stone of a certain granularity, which is sprayed with special devices on the surface with air pressure and high-speed causing dynamic compression.
