“…Best and Polivka (1959) and Van der Wegen and Bijen (1985) as shown in Figure 5.6. However, the specific creep of CNF-LCC is greater than the results of NWC obtained from Tang et al (2014) and Wendling et al (2018), which may be attributed to the lower compressive strength of CNF-LCC. Similar results are obtained when CNF-LCC is compared with LWAC.…”

“…Figure 5.7 shows that CNF-LCC exhibits comparable or lower specific creep than LWAC of similar strength measured by Best and Polivka (1959) and Van der Wegen and Bijen (1985).

“…At the same time, the same curing and testing condition make CNF-LCC samples reach hydral equilibrium with the surrounding environment before the load application and it can reduce the drying creep (Neville, 1959). Furthermore, it is found that the humidity of testing condition for CNF-LCC (70% RH) was higher than those summarised in Table 5.2 and this may decrease the creep behaviour (Wendling et al, 2018, BSI, 2004. accurate results in the prediction of long-term creep than EC 2 model.…”

“…us, investigation on the effect of curing temperature on cracking resistance of early-age concrete must be further studied [7]. e general trends [8] observed indicated that the American Association of State Highway and Transportation Officials (AASHTO) method tended to overpredict shrinkage for both concrete mixtures, especially at early ages, and no method accurately represented the lower shrinkage rate of lightweight self-consolidating concrete (LWSCC). Benboudjema et al [9] pointed out that the drying process caused a strong structural effect: microcracking arises in the concrete skin and attenuates the free drying shrinkage strain.…”

Massive self-compacting concrete pumped in steel tube columns has been used more and more widely in super high-rise buildings and bridge engineering at present. The early-age expansion and shrinkage performance of its core mass concrete is an important index to ensure the stress state of triaxial compression and structural safety. However, no relevant reports have been found. In view of the actual building with the height of 265.15 meters, the early-age expansion and shrinkage tests of the massive self-compacting concrete pumped in full-scale columns with the height of 12.54 m and 12.24 m and diameter of 1.3 m and 1.6 m were carried out by means of strain gauges embedded in concrete-filled steel tubes (CFSTs). The early-age variation regularity of the vertical and horizontal expansion and shrinkage strains for the core concrete with the diameter of steel tube, development time, temperature, the pouring pressure, expansion stress, and so on is given. The calculation model of its early-age deformation strains is presented in this paper, which is in good agreement with the experimental results. It provides the basis of experimental and theoretical analyses for shrinkage compensation of massive self-compacting concrete pumped in steel tube columns.
