چکیده انگلیسی
Both cylinder sizes demonstrated comparable values of hardened porosity (ÏÂ =Â 16 percent) and hardened density (DÂ =Â 2.11Â kg/m3), as well as strong linear Ï-D correlations (R2 range 0.60-0.90). The values of D agree well with those of the fresh density (two percent or less difference), which confirmed the suitability of the implemented casting and compaction procedure. Small cylinders presented higher 28-day fâ²c than large cylinders by 7.7 to 19 percent, depending on the curing category. The two-week air followed by two-week moist curing (2A2Â M) method yielded the highest 28-day fâ²c for both specimen sizes, however, longer periods of moist curing did not result in higher strengths. Cylinders from 1A3M, which were exposed to the longest moist curing, demonstrate the lowest fâ²c. Thermogravimetric analysis (TGA) confirmed the trends seen in 28-day fâ²c and proved (that) longer moist curing resulted in the loss of C-S-H and Ca(OH)2.
