“…Similar to the abovementioned AS and DS behaviors, the increment rate of TS tended to be higher at early curing ages and then lower afterward. The high rate of shrinkage at the beginning reflects the surface tension of the water that drained from the capillary pores in the system, 58 while the low rate of shrinkage at later ages is attributable to water loss due to surface absorption into the mixture. 59 In this study, O6000 exhibited a higher TS value than either S6000 or H6000.…”

Despite the fact that densified mixture design algorithm (DMDA) has been identified as a promising tool for green concrete mix design, its use in real practice has still been minimal worldwide. Due to the lack of precise information on DMDA computation in earlier studies, this work proposes DMDA including fly ash and ground granulated blast-furnace slag as a viable way to improve the long-term performance of green concrete. To encourage the use of DMDA, this study offers a detailed description of the DMDA mix design, as well as a step-by-step standard operating procedure and an empirical example of the computation. Assessments of the long-term performance of green mixtures (self-consolidating concrete and high-performance concrete) and ordinary Portland cement concrete (designed using the conventional method of American Concrete Institute, ACI) were made. Performances of the ACI (O6000 mixture) and DMDA concretes (S6000 and H6000 mixtures) were then compared in terms of compressive strength, elastic modulus, shrinkage, and creep strain. As a result, all of the concrete samples attained the target strength of above 41 MPa (6000 psi) after only 28 days. Moreover, compressive strength, elastic modulus, shrinkage, and creep strain increased significantly in all of the concretes over curing time. Importantly, the experimental results confirmed that both types of DMDA concrete exhibited higher compressive strength and better long-term performance than the ACI concrete under elastic modulus, creep, and shrinkage aspects.

“…Environmentdependent creep tends to compensate for an increase in temperature strain [3]. Atmospheric temperature is an important factor in shrinkage strain [4]. High temperature increases its influence, even since mixing.…”

The relationship between surrounding temperature and deformation behaviour of one full scale concrete plate with compressive strength of 60 MPa was presented in this paper. This research was done in Indonesia. Indonesia presents humid tropical weather. A specimen measuring 3.00m × 1.60m × 0.15m was used. Deformation was obtained by using four embedded vibrating wire strain gauges. The range observation is held between 7 to 28 days. The peaks of deformation follow peaks of surrounding temperature. Some deformation peaks time occur after surrounding temperature peak time, it is called as delay time. As a result, there is a linear relationship between temperature and deformation. The relationship was influenced by a factor which presented its position and delay time. The average error of this model is less than 15% at the age range of 7 until 14 days, and less than 50% at the age range of 15 - 28 days.
