“…The reinforcement of the cement materials by fibres constitutes an obstacle to any shrinking movement which occurs mainly within the cement paste. In general, the results found in this study are in agreement with those obtained in other works [11][12][13][14][15][16]. Under hot-dry conditions, the mortars reach the most important shrinkage by comparison with the laboratory conditions.…”

“…shrinkage and drying shrinkage, and Mechtcherine et al [18] summed up the mechanisms of these shrinking. In plastic stage, the underlying reason for shrinkage is the rapid loss of water from the concrete surface by evaporation and the physical process of capillary pressure build-up [87,88]. The mechanism of dry shrinkage is similar with plastic shrinkage, but the former is thought usually to occur in the harden stage.…”

High performance cement-based materials, such as high or ultra-high performance concrete (HPC or UHPC) have been widely used and still faces the risk of cracking caused by shrinkages, especially autogenous shrinkage. Internal curing is an effective method to reduce or even eliminate autogenous shrinkage and has effects on chemical shrinkage, dry shrinkage, etc. The commonly used internal curing materials include super-absorbent polymer (SAP) and porous materials. Porous materials refer to lightweight aggregate (LWA) and porous superfine powders. In this paper, the internal curing materials has been divided into two categories based on water absorbing mechanism. The effects of these two categories of internal curing materials on shrinkage of high performance cement-based materials are reviewed. The addition of internal curing materials releases internal curing water, postpones the drop of internal RH, and reduces autogenous shrinkage, but increase chemical shrinkage. The addition of internal curing materials with extra water increases drying shrinkage. The mechanisms of shrinkage on internal curing are also summarized and discussed. However, those mechanisms only focus on certain type of shrinkage. To reduce the risk of cracking more effectively, the relationship of different type of shrinkages should be established.

“…Boshoff and Combrinck [10] proposed a model to predict the degree of plastic shrinkage cracking. e model was based on the volume of water that evaporates from the concrete between the placing and the initial setting time of the concrete.…”

Concrete exposed to hot climatic conditions is prone to plastic shrinkage after casting within the first few hours due to the water evaporation and restraining conditions of concrete. This cracking is more commonly observed in concrete elements with a large surface area exposed to drying. In this research, plastic shrinkage of 13 self-compacting concrete samples with different cement paste volumes and various coarse to total aggregate ratios was studied. Test specimens of fresh concrete were subjected to a wind tunnel, which simulated hot dry environmental condition immediately after casting. It can be observed from the test results that the relationship between free plastic shrinkage and the difference between bleeding and evaporation is direct and linear. Finally, a model for plastic shrinkage estimation was suggested by considering the effect of free plastic shrinkage strain, restraining factor, and tensile strain capacity of self-compacting concrete.
