TECHNICAL PERFORMANCE
- Air Entrainment
The tested mortar formulation achieved 21.3% air content, demonstrating Carbocrete’s air-entraining capability under the evaluated conditions.
Air incorporation can contribute to mortar volume yield, reduced fresh density and improved application characteristics, depending on the formulation.
- Mechanical Performance
At 28 days, the tested formulation achieved:
- Compressive strength: 5.9 MPa
- Flexural strength: 1.93 MPa
These results demonstrate that the evaluated mortar achieved measurable mechanical strength alongside significant air incorporation.
- Workability and Consistency
The mortar presented a flow table consistency of 252 mm and a slump of 125 mm, providing useful reference values for formulation development and application assessment.
- Adhesion Performance
The laboratory reported the following tensile adhesion results at 28 days:
- Substrate adhesion: 0.20 MPa
- Surface adhesion: 0.24 MPa
Both results were classified as RA1 and RS1, respectively, under the classification presented in the laboratory report.
