DESCRIPTION

This CCPA standard specifies the test method for determining the compressive strength of sprayed concrete using the penetration resistance method, both in the laboratory and on construction sites.

This CCPA standard is applicable to the assessment of sprayed concrete with a compressive strength ranging from 1 MPa to 30 MPa.
