7. Physical and chemical properties of geopolymer cements
Shrinkage during curing: < 0.01%, non-quantifiable (figure 10 )
Compressive strength (uniaxial) : > 90 MPa at 28 d (for high-strength initial formulation, 20 MPa after 4 h; figure 11 )
Flexural strength: 10-15 MPa at 28 d (for high initial strength 4 MPa after 24 h)
Young's modulus: > 2 GPa
Freeze-thaw: mass loss < 0.1% (ASTM 4842), strength loss < 5% after 180 cycles
