Abstract

A system and method for applying a construction material is provided. The method may include mixing one or more of 4%-45% volcanic rock by weight, greater than 0%-40% latent hydraulic material by weight, 10%-45% alkaline component by weight, and 20%-90% aggregate by weight to produce a dry binding agent mixture, using a dry mixer; and combining the dry binding agent mixture with water at a nozzle to produce a sprayable concrete compound.

Claims (9)

1. A method for producing a sprayable concrete compound,

comprising:

mixing one or more of 4%-45% non-pumice based volcanic rock by weight, greater than 0%-40% latent hydraulic material by weight, 10%-45% alkaline component by weight, and 20%-90% aggregate by weight to produce a dry binding agent mixture, using a dry mixer; and

combining the dry binding agent mixture with water at a nozzle to produce a sprayable concrete compound.

2. The method of claim 1 , wherein the dry binding agent mixture includes less than 1% sulfate by weight.

3. The method of claim 1 , wherein the dry binding agent mixture includes less than 5% calcium by weight.

4. A method for producing a moldable concrete compound comprising:

mixing one or more of 4%-45% non-pumice based volcanic rock by weight, greater than 0%-40% latent hydraulic material by weight, 10%-45% alkaline component by weight, and 20%-90% aggregate by weight to produce a dry binding agent mixture, using a dry mixer; and

combining the dry binding agent mixture with water using a planetary mixer to produce a moldable concrete compound.
