“…In the recent years, there is a growing interest in investigating the effect of curing conditions on the mechanical and transport property of high performance concrete (Robins and Austin 1997;Tasdemir 2003;Shafiq and Cabrera 2004;Turk et al 2007;Zhao et al 2012;Ferreira et al 2012;Siddique 2013). Most of these studies focused on the ordinary strength concrete with mineral admixtures.…”

This paper presents the results of an experimental study conducted to evaluate the effect of curing conditions on the properties of normal and high strength concrete (NSC and HSC) with and without pre-wetted lightweight aggregates (LWAs). Cylinder specimens were drilled out from square concrete slabs subjected to four curing regimes (i.e. standard, water, natural and sealed curing) respectively, and then tested to obtain the compressive strength after 60 days. Three discs cut along the height direction of cylinder specimens (top, middle and bottom) were used to orderly measure the ultrasonic pulse velocity (UPV), open porosity, water absorption and splitting tensile strength. Afterwards, the comprehensive evaluation index, i.e. relative curing efficiency (RCE), was proposed based on the testing results above to quantitatively assess the effect of curing conditions on the physical properties of concrete. The experimental results indicated that curing conditions significantly influence the strengths and durability-related properties of NSC and HSC. The linear correlation can be obtained between sorptivity and open porosity of concrete under various curing conditions. Furthermore, in terms of the RCE analysis, the durability-related properties are more sensitive to the curing conditions than strengths for NSC and HSC.

“…The cement hydration products (CH and C-S-H) could be converted into calcium carbonate, calcite, modified C-S-H gel, or polymerized silica gel in a short period of curing time, thus contributing to microstructural development, reduction in pore size and total pore volume, and increase in apparent density and mechanical strength [28][29][30]. Besides, water curing was commonly used for ensuring available moisture for prolonged cement hydration inside the matrix such that continued formation of C-S-H gel could reduce the porosity and enhance the mechanical strength [31,32]. On the other hand, previous studies showed that coal bottom ash (CBA) [33,34], recycled concrete aggregate (RA) [35,36], crushed glass (CG) [37,38], and municipal waste incineration bottom ash (MIBA) [7,39,40] were relatively inert materials and suitable for replacing natural aggregate.…”

“…14 In study, 15 ordinary curing (20 ± 1°C) was beneficial for cement-based composites blended with metakaolin. Generally, the curing conditions affected the development of the properties of ordinary cementbased composites, 16 composites modified by fly ash, 17 composites modified by recycled aggregates 18,19 and a composite's long-term compressive strength. 20 This was also the case under hot JOM, Vol.…”

“…21 Of note, high air temperature and low humidity caused water to evaporate from a fresh cement-based mixture in a mold. 7 Watercuring conditions can effectively reduce this problem, 16 as is also the case in cement-based composites with mineral admixtures. 22 Salhi et al 23 reported that an increase of temperature and decrease of humidity increase the evaporation rate in SCC.…”

The goal of this article is to study the effect of curing conditions on the properties of cement-based composites blended with waste marble dust (WMD). WMD was added to cement-based composites with different ratios of replacement, and two of the most commonly used curing conditions were applied. Half of the composites were cured in water at a temperature of 20 ± 1°C, and the other half of the composites were cured in air at a temperature equal to 22 ± 2°C and relative humidity (RH) equal to 20 ± 1%. To achieve the goals of the study, the composites were tested after 3 days, 7 days, 28 days, and 65 days of curing for their apparent density (! ad), porosity (p m) and compressive strength (f cd). Finally, the obtained macroscopic observations were validated using scanning electron microscopy. It was found that the water curing conditions were beneficial for the cement-based composites and gave satisfactory results compared with the air-curing conditions.
