Strength• Based on 289 observations of moist-curedhigh-strength concrete samples made withType III cement, Mokhtarzadeh and Frenchobtained the following relationship[f cm= f c28⎛⎝t0.89 + 0.97t⎞⎠
Long-term strength• Iravani and MacGregor suggested the followingstrength values for sustained loading:• 70 to 75% (of the short-time loading strength) for65 MPa concrete• 75 to 80% for 95 MPa concrete, without silicafume• 85 to 90% for 105 MPa concrete, with silica fume• 85 to 90% for 120 MPa concrete, with silica fume
