In this study, internal curing by superabsorbent polymers (SAP) is utilized to mitigate self-desiccation and autogenous shrinkage of alkali-activated slag (AAS) pastes. Absorption desorption kinetics SAP incorporated in AAS pastes were studied with X-ray tomography. Internal delayed the peak rate heat liberation but increased total reaction degree mitigated effectively drop relative humidity self-desiccation-induced The cracking tendency undergoing restrained conditions was also...
Growing interest is awarded to the digitalization of building permitting use case and many works are developed about topic. However, subject very complex aspects usually tackled separately, making it hard for traditional literature reviews grasp actual progress in overall This paper unveils detailed state art Digital Building Permitting (DBP) by critically analysing means a set coding tags (research progress, implementation, affected DBP workflow steps, ambitions addressed) assigned...
Building Information Modelling (BIM) methodology is becoming widespread with many potential uses, such as facility and asset management for new buildings. Recently, it has also been applied the maintenance of built heritage, within so-called Historical BIM (HBIM) field. A model, empowered by detailed embedded information, an excellent tool to monitor infer on behaviour, performance deterioration heritage buildings, collecting classifying diverse data that can co-exist in model. However,...
Masonry building aggregates are complex historical structures comprising interconnected buildings. The safety of each depends not only on its structural integrity but also the interactions with neighbouring and their collective performance. assessment such constructions can benefit from BIM methodology. latter eases modelling complicated solid geometries assigning mechanical properties information essential for developing a reliable finite element model. Thus far, to analysis procedures...
Abstract The design of concrete structures is based on calculation rules, which often do not take into account the very early age behaviour material. However, during this period, structural subjected to strains due hydration process cement. If these are restrained by itself or surrounding boundaries, stresses start build up that can lead formation cracks. Among parameters involved in stress up, stiffness evolution major importance. This paper reports use eight different techniques aimed at...
This study investigates the influences of internal curing on reducing autogenous shrinkage alkali-activated slag/fly ash (AASF) paste. The with superabsorbent polymers (SAPs) reactions and microstructure AASF paste are investigated. It is found that SAPs absorb liquid mainly before initial setting time Afterwards, gradually released, keeping relative humidity close to 100%. can significantly mitigate paste, especially after acceleration period reaction. mitigating effect due mitigated...
Mass foundation slabs represent unique structures because of the considerable thermal effects generated by exothermic reactions cement hydration that occur during concrete curing. Arising temperature variations in early age generate tensile stresses may reach values resulting cracking slabs. That is why a realistic estimation early-age loads and induced essential engineering science practice. In this work, several alternative methods can be used assessment risk have been thoroughly reviewed...
