“…In this regard, the steaming duration is important. The preceding researches mostly spent 24 hours for the steam curing which was considered sufficient and effective in the strength enhancing [13][14][15]. Therefore, the heat cycle (1 day cycle) was also used in this research.…”

This research is to study the effect of mortar mixed with shrinkage reducing agent (polyoxyalkylene alkyl ether type), expansive additive (CaO type), and fly ash (hereinafter "SRA," "EX," and "FA," resp.). Moreover, steam curing was studied to improve the properties of mortar. The plastic shrinkage test was conducted by using the strain gauge embedded at 0.5 cm from the surface according to the ASTM C1579-06 standard within early age followed by the total shrinkage test and compressive strength test. The test results showed that mixing both the EX and SRA increases the plastic enlargement of the mortar during the early age more than using either the EX or SRA solely. The steam curing helps to reduce the plastic shrinkage when the mortar is added with the FA and SRA while adding the EX increases the enlargement compared to the normal curing. When the EX, SRA, and FA are all added to the mortar mixing, great attention should be paid due to the increase of greater enlargement. For the compressive strength view, the steam curing increases the compressive strength in all types of mixture. The steam curing significantly helps increasing the compressive strength of mortar with combination of EX, SRA, and FA. Nevertheless, the XRD and SEM tests explain such enlargement accordingly.

“…The most important improvement is product ready for use within 24 h (the strength is generally equivalent to 28 days under ambient curing). However, this curing method alters the properties of the resulting concrete (American Concrete Institute 1963;Boukendakdji, Brooks and Wainwright, 1996;Ho, Chua & Tam, 2003;Erdem, Turanli & Erdogan, 2003). Although plenty information is already available on the effect of steam curing on conventional concrete properties, there is limited data relating with steam cured concrete pavement blocks prepared with fly ash.…”

In this study, influence of curing condition and fly ash content on properties of pre-fabricated concrete interlocking blocks (PCIBs) were investigated. The blocks were produced with crushed sand stone (fine) and crushed stone (coarse) as aggregate. Also, fly ash was added to mixtures in different ratio by replacing the cement from 0 to 30%. PCIBs were cured in three different types as steam cure, water-pool cure and wet cure. Compressive strength, tensile splitting strength, density, apparent porosity, water absorption by weight and abrasion resistance of PCIBs was determined. When comparing the PCIBs, the use of wet cure results in lower physical and mechanical properties after 28 days. By contrast, waterpool and steam cure gives better result on mechanical and physical properties. Also, replacement of cement with fly ash (from 10% to 20%) has a significant effect in increasing important properties of PCIBs.Keywords: Curing; pavement blocks; prefabricated; strength; mineral admixture. ResumenEn este estudio, la influencia de la curación de la condición y el contenido de cenizas volantes sobre las propiedades del hormigón prefabricado Bloques entrelazados (PCIBs) fueron investigados. Los bloques fueron producidos con arena de piedra triturada (fina) y piedra triturada (grueso) como agregado. Además, cenizas fueron añadidas a las mezclas en diferente relación, reemplazando el cemento desde 0 a 30%. Los PCIBs fueron curados en tres tipos diferentes como: cura de vapor, piscina de agua cura y cura húmeda. Resistencia a la compresión, resistencia a la tracción indirecta, densidad, porosidad aparente, absorción de agua por el peso y la resistencia a la abrasión de PCIBs fue determinadas. Cuando se comparan los PCIBs, el uso de la cura húmeda se traduce en la reducción de propiedades físicas y mecánicas, después de 28 días. Por el contrario, la piscina de agua y vapor cura da mejor resultado en las propiedades mecánicas y físicas. Además, la sustitución de cemento con ceniza volante (del 10% al 20%) tiene un efecto significativo en el aumento de propiedades importantes de PCIBs.Palabras Claves: curado; bloques de pavimento; prefabricado; fuerza; adición mineral.

“…Steam curing method is a kind of curing method using high curing temperature, which is simple and provides easy operation. It is often used in the production of precast concrete elements [9]. However, Wang et al [10] found that elevated temperature curing at early ages has some negative effects on the late-age properties of concrete.…”
