concrete spraying

Concrete is the most versatile substance used in the construction work, which is either sprayed or poured. Spraying concrete is popular than pouring because of its several features. Here, we have discussed benefits of spraying concrete.

There are two methods of spraying concrete Dry-Mix (Gunite) and Wet-Mix (Shotcrete). In Shotcrete concrete pumping process water mix fluid is transferred through hose and projected at high speed onto a surface and in Gunite Concrete Pumping process dry mix concrete is sprayed. This method of concrete pumping has replaced the traditional methods of lining tunnels.

Let Us Discuss Its Properties And Applications:

Spraying concrete shows some properties that in some respect make it superior than poured concrete. These properties are result of different methods of mixing, transporting and placing instead of fundamental differences in component materials.

  • Low Water/Cement Ratio: Spraying concrete generally has a lower cement/water ratio than poured concrete. It is true in the dry process where a low slump mix capable of supporting itself without drooping.
  • High Strength with Quick Strength Gain: It is expected to acquire high compressive strengths with low water/cement ratio and the dense compaction is attained by the high velocity of application.
  • High Density/ Low Permeability: High Velocity of placement ensures good compaction and high density coupled with low permeability and water absorption. It results in durable homogeneous material with excellent freeze resistance.
  • Enhanced Adhesion and Bond Strength: When mixture is properly prepared then bond strength with spraying concrete is superior.
  • High Speed High Output: It delivers high volume rapidly and economically. Free form tunnel linings or retaining walls can be sprayed soon after excavation.
