The same concrete specimens were tested at 7, 28 and 90 days. At 7 days, all mixes have elastic modulus values just below or just above 40 GPa, and the difference is small between the highest value of 41.6 GPa from the reference mix R1 and lowest value of 36.8 GPa from the reference mix R2. At 90 days, all mixes have values clustering around 45 GPa. Similar trends are observed in the case of the 0.55 w/b ratio mixes (Fig. 4) with similar elastic modulus values as in the case of the 0.4 w/b ratio mixes with the same binder proportions. In general, all these mixes have similar E-Mod performance. In general, results indicate that the elastic modulus of concrete depends largely on the amount and the stiffness of the aggregates and less on other factors such as concrete strength or cement paste. Drying shrinkage Figure 5 presents the development of shrinkage strain in the concrete specimens with w/b = 0.40. Based on the results, Fig. 4: Elastic modulus development of LC3 mixes and reference concrete mixes (w/b = 0.55).86-411-86715816cnkonic@konic-gearbox.comhttps://konic-gearbox.com/Konic Gearbox(Dalian)Co..
